SYSTEM FOR PREPARING LIQUID SAMPLES FOR TESTING Russian patent published in 1995 - IPC

FIELD: testing of materials. SUBSTANCE: program unit controls operation of individual drives of chemical reagent 10 and sample 11, hydraulic distributor 13, outlet valves 3, 7 and 17 when receiving signals from detectors 2, 5, 6 and 14 mounted in receiving, draining and indicator chambers 1, 4 and 15 correspondingly. Accelerated drainage of the solution tested is provided from measuring cell 16, residuals of previous sample are removed and washed away from separate units and manifolds of the system. After that the new sample is prepared and supplied into cell 16. Chemical reagent is used effectively due to reduction in volume of solution supplied for testing. EFFECT: improved efficiency. 3 dwg
