Abstract Trace gas transfer technique is a new technique with the advantage of convenience and quickness. It decreases dilution times during the preparation of gas CRMs, while keeping weighing accuracy, specially applied to prepare gas CRMs with lack of component gas or multi-dilution. The theory and operating process of this technique is introduced, furthermore, the reliability is verified by experimental data.
