Sample injection apparatus comprises measuring instrument into which sample is injected, sample valve, rinse-discharge valve, and timing units

摘要

A sample of a substance in a carrier fluid is inserted into a measuring instrument (4). The fluid travels through a sample valve (V1) controlled tube through which it is allowed to flow for a given period determined by a timing unit (T2). Following sample discharge, a rinse agent flushes the tube entering via a rinse-discharge valve (V2). A sample of a substance in a carrier fluid is inserted into a measuring instrument (4). The fluid travels through a sample valve (V1) controlled tube through which it is allowed to flow for a given period as defined by a timing unit (T2) and reaching a filling level M. Following discharge of the sample, a rinse agent flushes the tube entering via a rinse-discharge valve (V2). The instrument filling level then reaches a new level S. Surplus fluids are then discharged. The timing devices (T1, T2) may be linked by an interface (11) with the control unit (12) and the sample generation system (15).
