1 THE RIGAKU JURNAL VL. 12 / N.1 / 1995 N-LINE MULTICHANNEL SIMULTANEUS X-RAY SPECTRMETER SYSTEM SIMULTIX 10S, SIMULTIX 11S 1. Introduction The Simultix 10S and Simultix 11S are new version of the Simultix 10 and Simultix 11, respectively. They are equipped with an automatic sample loading mechanism at the sample inlet port. Samples from an automatic sample pretreatment device are automatically loaded onto a dedicated sample holder located at the sample loading mechanism. After the completion of analysis, the samples are automatically discharged from the dedicated holder. Because unattended analysis is performed in this way, manpower is saved and even faster analysis is feasible. The following sample pretreatment devices are available: an ingot grinding/cutting system, crushing and shaping system, glass bead sampler, liquid dripping system, polymer hot press system and so on. 2. Features (1) Manpower Saving by Using Various Sample Pretreatment Devices a) Automatic bead sampler (electric furnace type, high frequency furnace type)... Cement, slag, etc. b) Automatic powder sample preparator (ASP)... Slag, sintered iron, etc. c) Automatic ingot grinder... Pig iron, cast iron, etc. d) Automatic ingot cutter... Copper alloy, aluminum alloy, etc. e) Liquid sample treatment device... Electrolyte, plating solution f) Automatic polymer shape... High polymer Vol. 12 No

2 List of Sample Pretreatment Devices (a) Automatic Glass Bead Sampler: Glass bead samples can be automatically prepared by just adding spoonfuls of sample. (d) Automatic Ingot Cutter: Nonferrous materials like aluminum, zinc, copper alloy, etc. may be cut into samples for analysis featuring high reproducibility. Automation of cutting and analysis is possible by combining this cutter with the Simultix. (b) Automatic Sample Preparator (ASP): A briquette sample can be automatically prepared by just approx. 30 to 50 grams of powder sample. The sample is pulverized to 200 mesh. By combining the ASP with the Simultrix, manpower savings can be made for the chain of work covering crushing, pressing and analysis. (e) Liquid Sample Treatment Device: A sample suitable for analysis is automatically prepared. A prescribed amount of solution, e.g. electrolyte, plating solution, etc. can be dropped onto a filter and dried. Control of the concentration of solution can be automated by combining the sampling system and the Simultix. (c) Automatic Ingot Grinder: The automatic ingot grinder turn out samples featuring high reproducibility. Automation of grinding and analysis is possible by combining with the Simultix. (f) Automatic Polymer Shaper: A maximum of 30 discs of polymer sample can I be automatically prepared by hot press when, approx. 6 grams of polymer is added per sample. 42 The Rigaku Journal

3 (2) Analytical Range Newly developed goniometer and analyzing crystals permit high-sensitivity and high-precision analysis covering Be through U. (3) Fast peration An automatic sample loading mechanism handles sample installation and removal to and from the sample holder automatically. (See 4. (1) verall View.) Also, sample conveyance from the sample inlet port to the measurement position is made by a new one-step motion device, leading to substantial speed-up of operation. (4) Automatic Calibration of Analytical System If a standard sample stocker (optional) is installed, system calibration (PHA adjustment, standardization) can be carried out automatically at the prescribed time by program run. (5) Safe Measurement of Powdery Samples and Filter Samples The pumping speed and the lead speed can be set according to the type of sample to minimize the potential scattering of powdery samples and filter samples. As a result, a long-term stable operation can be maintained. Further, a powder sample attachment (optional), if utilized, can significantly keep fine particles from mixing into valves and vacuum pumps. (6) Safe Maintenance (1) The status of the analytical system can be known easily through regular display of its running condition. Besides, plentiful maintenance functions are provided. (2) In case of a trouble, the substance and cause of that abnormality are displayed to enable the operator to check and fix it promptly. (3) A remote diagnostics function (optional) is provided to reduce the repair time. 3. Sample The following are the major types of samples for measurement with the on-line type Simultix.

Pushing the sample to the inlet port from the origin point. (transfer operation) 3. Conveyance from the inlet port to the analysis position. Then after analysis, return to the inlet port again. (sample internal conveyance? analysis? take-out) 4. Sample discharge (arm UT chute, vibrator operation) 44 The Rigaku Journal

5 (3) Function of Each Part IN-belt : Carries a processed sample to a transfer mechanism consisting of an arm, stopper and pusher. The sample diameter is then measured on the belt and if there is any sample whose diameter falls short of specification, the pusher is moved to the transfer retreat position and then the sample is discarded by driving of the IN-belt. Moreover, if another sample does not pass through the sample dia. counter within a certain period after the IN-belt drive, it is regarded as an error. Transfer : Carries a sample, which has been halted by a stopper, to each position with the aid of the pusher (arm). The transfer stop positions are called respectively the origin point, transfer retreat position, inlet port and sample discharge position in sequence from the bottom in the illustration. Slot for discard: A bead sample or the like which is broken during conveyance will be discarded through the slots. Leveler : A mechanism to load samples on the on-line sample holder, A cradle of the online sample holder is vertically moved by the leveler in order to load on-line samples on the online sample holder. The leveler moving amount that depends on the sample thickness is mechanically fixed. UT chute: A sample-discharging device. After the sample is sent out to the discharge position, it is discharged through the chute, while being vibrated by a vibrator. UT belt : Carries the sample received from the chute to another position. This device is optional. 5.
