ISO GUIDE 34 CERTIFIED REFER ENCE MATERIAL ULTRAGOLD ISO GUIDE 34 CERTIFIED REFERENCE MATERIALS (CRM) As technology improves and regulatory bodies keep pace with identifying new analytes and detection limits and setting new regulatory requirements, certified reference material producers must stay ahead of the curve with better-defined standards and calibrators with validated and stated uncertainties. In the absence of ISO Guide 34 CRM, laboratory technicians assume the arduous and time-consuming task of assessing and documenting the uncertainty of calibration standards in use. ISO Guide 34 Accreditation requires the CRM manufacturer to identify and document the major components of uncertainty including homogeneity, short-term stability, long-term stability and the uncertainty due to analytical characterization. ULTRAgold fulfills international need with ISO Guide 34 CRM at ideal concentrations of 1000 and 10 ppm for a complete line of inorganic standards. All products are provided with an ISO Guide 34 Certificate Analysis, prepared according to ISO Guide 31.

ULTRAcheck ULTRACHECK BLIND QC CHECK STANDARDS ULTRAcheck is a series of blind quality control standards used to check whether or not an analytical system is in control. ULTRAcheck samples are designed to mimic real-world samples for specific EPA methods, and are run as blind samples. The analytical data generated using the method is then compared to the true values supplied with the ULTRAcheck standard. Agreement between the data generated for ULTRAcheck used as a blind sample and the true values of the ULTRAcheck standard indicates that your analytical system is in control. Use ULTRAcheck on a Regular Basis to: Train and qualify personnel Establish and maintain EPA method proficiency Verify analytical system accuracy and precision Prepare for next state or EPA environmental audit ULTRAcheck true values are provided in a separate, sealed envelope. The envelope can be sent to another site, upon your request. Data obtained using the ULTRAcheck blind sample can be immediately compared against the true values supplied. Complete instructions are included with each sample. Know Your System is in Control The analytical system is shown to be in control when the data generated for the ULTRAcheck blind sample falls within the advisory range listed on the ULTRAcheck certificate of analysis If the data generated for the ULTRAcheck blind sample does not fall within the advisory range, immediate corrective action can be taken prior to proficiency failure and loss of accreditation TABLE OF CONTENTS ULTRAcheck Documentation...45 Inorganic Blind QC for WS Drinking Water Analysis...51 Inorganic Blind QC Samples for WP/DMR-QA Non-Potable Water...56 ULTRAcheck Organic Blind QC Samples for WP Non-Potable Water Analysis...58 Non-Potable Water Analysis...60 ULTRAcheck Blind QC Samples for Underground Storage Tanks (UST), Hydrocarbon Fuels, & Total Petroleum Hydrocarbons (TPH)...64 ULTRAcheck Blind QC Samples for Aroclors...65 ULTRAcheck Blind QC Samples for the EPA Cluster Rule...65 44 TOLL FREE 800-338-1754 CALL 401-294-9400 FAX 401-295-2330
