ABSTRACT:
A method of testing an analyzer to determine the accuracy thereof and a volumetric primary standard apparatus for doing same, the method of which includes flowing a carrier gas stream at a known flow rate, periodically injecting a measured quantity of sample gas at a selected interval into the carrier gas stream, homeogeneously mixing the carrier gas and the sample gas therewith in a mixing chamber for providing a homogeneous mixture of sample gas and carrier gas and thereafter flowing the homogeneous mixture into an analyzer whose accuracy is to be tested.
