ANORDNING FOR KVANTITATIV ANALYS

摘要

An apparatus for the quantitative analysis of a fluid, which employs the same fluid to generate a null signal, a calibration signal and a measuring signal. A calibration source adds a known amount of constituents to a carrier fluid, derived from the original fluid calibration purposes. A cleaning filter extracts unwanted components from the carrier fluid so as to prevent contamination or chemical attack of the injection zone.
