SYSTEM FOR HIGH-EFFICIENCY LIQUID CHROMATOGRAPHIC ANALYSIS WITH FLOW DETECTOR

摘要

FIELD: chromatographic analysis of liquids. SUBSTANCE: system for high-efficiency liquid chromatographic analysis with flow detector includes pump, flow transducer with output signal U_F, device for injection of sample, thermostating high-efficiency chromatographic column, flow chromatographic detector with output signal U_D, device recording output signal of analysis system and interface coupling detector to device recording output signal of analysis system with input signal U_S. Device forming output signal of detector is placed between output of detector and input of interface. Input signal U_S of interface is related to output signal U_D of detector and output signal U_F of flow transducer by equality U_S= U_D/U_F. EFFECT: increased accuracy of chromatographic analysis. 1 dwg
