3 Methods of Analysis Colorimetric Methods These tests are generally simple and easy to run the basic concept is one of adding a specific reagent which reacts with the analyte being tested to create a color. The intensity of this color is then measured. You can visually compare the intensity of the color developed against a known standard with our Aqua Comparator or Comparator 705. Or for even better accuracy, you can measure the color using a colorimeter (see our SC400, 942 or MC500) or our SP600 Spectrophotometer. As you will see, Orbeco-Hellige has a full line of colorimetric water quality tests. Titrations Titrations are simple chemical tests in which a solution or tablet of a known concentration is added slowly to a sample of unknown concentration. At a given point, (called the end point) the color of the sample will rapidly change, such as from red to blue. An easy calculation will then allow determination of the concentration of the analyte. Orbeco s MiniKits (Page 8) are convenient, innovative titration kits that use tablets as the titrant. Electrochemical Methods Some parameters in water such as ph, ORP and Conductivity can be measured using an electrochemical meter. These are precise instruments which (in effect) measure the flow of electricity through a water sample. In addition, other electrochemical instruments can measure Dissolved Oxygen in the sample using membrane technology. Orbeco s line of Electrochemical Instruments can be found starting on Page 76 of this catalog. 2 Phone: / Fax:

4 Orbeco-Hellige, Inc Parkland Drive Sarasota, FL Respirometric Methods BOD is a measurement of the oxygen update (or demand) of microbiological organisms in a wastewater sample. Orbeco- Hellige offers an innovative product called the Oxi700 which allows precise BOD measurement without error prone sample dilutions. In addition, it can start providing BOD data within 1 day of initiating the test. The Oxi700 can be found on Page 72 of this catalog and is the perfect tool for process control purposes. Turbidimetric Methods Turbidity is basically a measurement of the cloudiness of the water. Sources of water cloudiness may include dissolved organic and inorganic materials. To meet US EPA guidelines, turbidity detection has to be done by measuring the diffraction of a white light source at a 90 degree angle. Orbeco offers several different turbidimeters, starting on Page 68. For more information about the Methods of Analysis, instruments, or reagents please contact our Customer Service department.

7 Minikits and Test Kits Highlights Easy to use with exact reagent dosing Cost effective Tablet reagents have a guaranteed shelf life of 5 years Easy and safe storage The MINIKITS are designed for rapid water testing. Most of the MINIKITS are based on titrimetric methods. Tablet Count Method: In the tablet count method, the liquid titration solution and indicator are replaced by Orbeco-Hellige tablet reagents. A specified number of tablets are added to a defined sample volume until a chemically induced color change takes place. The concentration of the parameter being measured is calculated from the number of tablets required. The measuring range can be expanded by varying the sample volume. Speed Test: The speed test is based on reverse titration. After adding a reagent tablet to a calibrated test tube, the water sample is added slowly until the color of the solution changes (i.e. from red to blue). The user can then read the result of the liquid level. Yes/No Test: A Yes/No test can determine if a specific ingredient is present in the water and/or if its concentration is higher or lower than a defined level. Arsenic Test Kit The Arsenic Test Kit is able to accurately detect very low ranges of arsenic, and can be used to determine the presence of arsenic in drinking water. The kit includes enough materials to perform 100 tests. Meets WHO requirements for drinking water. This Test Kit is able to detect levels as low as mg/l Arsenic. To minimize the potential danger to the user, the Test Kit does not use a highly toxic lead acetate for sulfide removal. Instead, the removal of interfering sulfide ions is integrated into the test procedure. To avoid irritation of the skin, the acid substance is in the form of a solid. The unbreakable plastic reaction bottle is safe and convenient for on-site testing purposes. During the test procedure, the developing arsine gas is tightly sealed inside the reaction bottle. Unable to escape, it cannot harm the user. P/N L Turbidity Method: A two-section calibrated tube is filled with sample and a reagent tablet is added. The reagent creates a level of turbidity that is proportional to the concentration of the parameter being measured. The inner tube, which has a black dot on its base, is lowered until the dot is obscured by the turbidity. The result is read from the water level in the inner tube. 6 Phone: / Fax:

Orbeco-Hellige, Inc. 6456 Parkland Drive Sarasota, FL 34243 39 The SP600 is a single-beam spectrophotometer.

40 Orbeco-Hellige, Inc Parkland Drive Sarasota, FL The SP600 is a single-beam spectrophotometer. The instrument performs a self-test as soon as it is turned on, confirming proper operation and performance of all key components. Using an innovative tungsten halogen lamp with flash function, the lamp is on only momentarily during the measurement process, eliminating a warm-up period. An integrated Didymium-filter confirms the instrument is working properly and assures data integrity. Using a unique holographically-produced monochromator, the light is split into special ranges, where a moveable mirror ensures that light of the desired proper wavelength is focused automatically as it passes through the water sample. The light not absorbed by the sample travels to the silicon photodiode detector. The signal is then evaluated by a microprocessor and shown as a direct-read result in the display Tungsten halogen lamp 2. Monochromator 3. Movable mirror 4. Sample chamber 5. Silicon photodiode 6.

A wavelength scan can be performed over a user-defined interval between 330 and 900 nm.

41 SP600 Spectrophotometer An innovative, multifunctional, sample chamber eliminates the need for most adapters. Round vials measuring 16 mm and 24 mm in diameter and rectangle cells with pathlengths from 10 to 50 mm do not require any adapter. Wavelength Scanning and User Calibrations. A wavelength scan can be performed over a user-defined interval between 330 and 900 nm. With this function, an operator can measure standards of different concentrations to create user calibrations of up to 10 order polynominal. New Methods. New test methods are always being added. Users can easily add new methods to their instrument by downloading free software from our website. Data Logging and Handling. An RS-232 connection allows for the instrument to be connected with a PC or printer. Each data point is recorded with the date, time, operator number, measuring range, and method number. The instrument is able to store up to 1,000 data points in its internal memory. Low Maintenance. The only required maintenance is the eventual replacement of the halogen bulb. Users will find this to be quick and easy, as the bulb is conveniently located at the back of the SP no tools required! Multi-functional Sample Chamber Measurement Methods. The user chooses the desired method either from the alphabetical method list or by entering a numerical code. The SP600 can easily provide additional information such as the required vial, reagent type, and measuring range by using the function keys. The date and time are shown in the display by pressing the clock button. The SP600 automatically selects the correct wavelength. Zero Test. The zero test is performed with the water sample by pressing the ZERO key. Countdown Function. Some tests require a waiting period after a reagent is added to the sample. The SP600 s countdown function keeps the time for you by continuously displaying the remaining time. With ten seconds left, an alarm alerts the user, and measurment begins automatically. The result is then shown on the display. The user can turn off the countdown function to allow rapid completion of a series of samples. AC or Battery Powered. The SP600 can be run on battery power with an available battery pack Phone: / Fax:

DPD liquid reagents should be colorless when fresh and may turn a brownish color if the reagent has deteriorated. The use of deteriorated products must be avoided as they will give false results. Our test tablets are manufactured in Germany under tightly controlled conditions on the State-of-the-Art machinery. Maintaining the highest quality standards allows us to guarantee our tablets for a minimum of 5 years, and some for as long as 10 years. Each tablet is hermetically sealed within an individual aluminum foil pocket, protecting against environmental conditions. This packaging keeps each tablet in perfect condition, right up until the time it is needed by the user. Test tablets remain the most consistent and reliable reagent format available, routinely outperforming other reagent formats, and delivering maximum accuracy for the user. Our new blister packaging brings adds convenience to the protection achieved in Orbeco-Hellige s long established tablet production technology. With the new blister strip, the user just pushes the tablet through the protective foil, straight into the sample. Simple, time-saving and practical. Each tablet is contained within an individually formed foil cup, lined with the latest aluminum composite material, and guaranteeing product performance. As a result of improved sealing efficiency, the blister pack has been reduced in size to 91 x 34 mm making them even more convenient for storage and shipping. BT is added to the end of the part number to identify the new style of packaging. (For example RT106-0BT). There are no safety risks if the tablets are used in line with the instructions supplied Phone: / Fax:

Tube tests Liquid reagents Powder Packs Orbeco-Hellige s tube tests enable the user to easily perform highly sensitive and precise water testing.

Tube tests contain a precisely measured amount of reagent, thereby avoiding the presence of extra chemicals and optimising test safety.

They are supplied in a storage and dispatch box together with the digestion or auxiliary reagents.

46 Tube tests Liquid reagents Powder Packs Orbeco-Hellige s tube tests enable the user to easily perform highly sensitive and precise water testing. Using tube tests measurements are considerably faster and easier, particularly in the case of standard and serial tests. Tube tests contain a precisely measured amount of reagent, thereby avoiding the presence of extra chemicals and optimising test safety. Up to six different measuring ranges are available for the various tests. The tubes are made of special optical glass with a 16 mm diameter. They are supplied in a storage and dispatch box together with the digestion or auxiliary reagents. This packaging unit contains 24 or 25 reaction vials and up to 2 zero vials for photometer system calibration. As a rule, liquid reagents are comprised of several components that need to be added to the sample in a certain order. As both the size and the number of drops have a decisive effect on the color complex result, the reagents need to be added with a high degree of precision. The shelf life of liquid reagents is reduced by temporary contact with oxygen when the bottle is opened, as well as by improper storage environments (presence of sunlight or high temperatures). Provided that the bottles are stored within the temperature range 43 F to 50 F, the Orbeco- Hellige DPD and Phenol Red solutions can be used for a period of one year from the production date. The fast and easy use of Powder Packs has made them extremely popular for water testing applications in many countries throughout the world. The Orbeco-Hellige Powder Packs provide users with a real alternative to existing measurement systems. The Powder Packs are produced with the same high quality standards as our tablet reagents. Parameters from aluminum and chlorine to sulphate are just some of the well-known tests that are included in the Powder Pack range. Their chemical properties are suitable for use with Hach-Colorimeter-Systems. Reagents Orbeco-Hellige, Inc Parkland Drive Sarasota, FL

66 Orbeco-Hellige, Inc Parkland Drive Sarasota, FL First Edition 65 The TR125 Thermoreactor is for chemical digestion of samples that require it, such as in the determination of COD, TOC, Total Phosphate and Total Nitrogen. The required temperatures and reaction times are pre-programmed, and easy to select by using the keypad. Users can pre-select reaction times of 30, 60 and 120 minutes or can set it to operate continuously. When digestion is complete, the reactor automatically turns off and will sounds an alarm. The Chemical Oxygen Demand (COD) test is widely used as a measure of organic contamination by determing the quantity of oxygen required for oxidation of reduced species including organic matter, in a water sample using a specific oxidizing agent, temperature and time reduction. COD testing is more reliable and is preferred to BOD testing as test results are more reproducible and are ready in two hours (or less) rather than 5 days. In addition, COD testing is a better indicator of organic pollutants in industrial wastewater containing cyanides and heavy metals. COD testing affords rapid response to changing conditions before critical problems develop. The TR125 COD reactor is fitted with 24 holes for 16 mm diameter vials.

Orbeco-Hellige, Inc. 6456 Parkland Drive Sarasota, FL 34243 71 The Oxi700 BOD System is a manometric respirometer that measures Biological Oxygen Demand according to Standard Methods 5210 D.

72 Orbeco-Hellige, Inc Parkland Drive Sarasota, FL The Oxi700 BOD System is a manometric respirometer that measures Biological Oxygen Demand according to Standard Methods 5210 D. The system includes: Complete unit with 6 sensor heads and control unit with batteries Inductive stirring unit with power supply 6 sample bottles 6 rubber gaskets 6 magnetic stirring rods, 1 overflow flask (157 ml) 1 overflow flask (428 ml) 1 bottle of potassium hydroxide solution (50 ml) 1 bottle of nitrification inhibitor solution (50mL) Instructions The Orbeco-Hellige sensor system is a 6 sample system that allows precise measurements of BOD based on the manometric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintaining a constant volume. The integral pressure sensors,make it unnecessary to use mercury for pressure measurements. Measuring ranges and sample volumes The BOD level of a sample depends on the quantity of organic matter present, which can vary considerably. The Orbeco- Hellige Oxi700 is calibrated for the various sample volumes and the corresponding measuring ranges listed in the table below. The overall measuring range of the system is mg/l. For all measuring ranges, BOD is shown directly in mg/l. O 2 CO 2 Pressure Sensor Seal cup Sample Bottle Waster Water Gas Phase How it Works Respirometric methods provide direct measurements of the oxygen consumed by microorganisms from an air or oxygen-enriched environment in a closed vessel under conditions of constant temperature and agitation. Carbon dioxide produced metabolically by the bacteria is chemically bound by the potassium hydroxide solution contained in the seal cup in the bottle. The result is a pressure drop in the system, which is directly proportional to the BOD value and is measured by the Orbeco-Hellige BOD sensor. The BOD level is then displayed directly in mg/l. The BOD values are stored in the sensor memory and can be viewed on the large-format display at any time without the need for time consuming conversion using factors. This means that test series that end on a weeknd can be evaluated during the following week. The measurement period is userselectable between 1 and 28 days to suit the application. While short measurement periods are useful for scientific applications, standard BOD measurements typically extend over a period of 5 days and manometric determination of OECD, for example, generally takes place over a period of 28 days. Oxi700 BOD System Range mg / L BOD Sample Volume ml

73 Oxi700 BOD System Temperature equalization Temperature equalization is essential prior to biological testing, as temperature has a major effect on biological activity. BOD measurements, for example, are always performed in a thermostatically controlled cabinet at a temperature of 20 C. Automatic start function Variations in sample temperature prior to testing result in pressure variations within the measuring system during the temperature equalization period in the thermostatically controlled cabinet (if BOD measurement is to take place at 20 C, for example). Such variations would normally cause errors during manometric measurement. In order to prevent such errors, the OXi700 BOD meter is equipped with an automatic start feature: measurement does not start until the temperature in the samples is the same as that in the thermostatically controlled cabinet. This rules out the possibility of temperature (and pressure) fluctuations that are not related to the manometric measurement Start Day 1 Day Day 1 Day 2 Day 3 Day 4 Day 5 Day 2 Day 3 Day 4 Day 5 Display 150 mg / l 220 mg / l 240 mg / l 250 mg / l 260 mg / l Evaluation of measurements If the measuring period is set at 24 hours, the Oxi700 BOD measuring system records a measurement once every hour. With a measuring period of 48 hours, the unit measures and stores a BOD value once every 2 hours. If the measuring period is between 3 and 28 days, one value is measured and stored each day. Current values and stored values may be called up at any time. The table/below illustrates an example of BOD 5 evaluation. The development of BOD over a period of 5 days is easily seen.
