Title: Dead time correcting method for gas analyzer
Inventor: KIHARA NOBUTAKA
IPC: G01N31/00
Filed: 1993-11-20
Abstract: PURPOSE:To accurately measure the dead time of a gas analyzer and to bring generation of NOx into coincidence with an acceleration region by inserting a probe of a gas analyzer to a tail pipe of an automobile, purging it with clean air, then switching it to a measuring state, and measuring a rising time of CO2 gas in exhaust gas. CONSTITUTION:The method for correcting the dead time of a gas analyzer comprises the steps of inserting the probe 2 of a gas analyzer 1 into the tail pipe 4 of an automobile 3, feeding clean air (a) from the analyzer 1 toward the probe 2 through a filter 7 by a bump 8, purging the gas in a system, then switching the analyzer 1 to a measuring state at a time t0 after the purging, and observing the rising time T of the pointer of a CO2 concentration measuring unit 5 to measure the dead time td from when exhaust gas G produced from the automobile 3 is passed through the probe 2 to when the gas G arrives at the concentration measuring units 5, 6. That is, the dead time is td=T-t0. The timing deviation between generation of the NOx and the acceleration region is corrected by using the measured time td.
