Preparation of Gas Standard Mixture of R134a by an Injection Method

Abstract:

An injection method was proposed for the preparation of R134a in N₂ gas standards at 10 nmol/mol. The standard gravimetric method of ISO6142 was used as verification for the injection method. Results showed that good consistence between the injection method and the standard gravimetric method could be obtained. The contribution of the injection method to the standard uncertainty was about 0.92%, almost in the same order of magnitude with contribution of the standard gravimetic method.
