초록

The present invention provides a process for producing standard gas mixtures which entails purifying a raw gas using a gas purifier (3) such as a known two stage gas purifier system, thereby generating a high-purity diluent gas; mixing the high-purity diluent gas and at least one high-concentration standard gas, by generating a medium-concentration gas mixture; dividing the medium-concentration gas mixture into a first flow and a second flow; selectively mixing the first flow with a sample gas or a high-purity diluent gas or a mixture thereof, thereby ob...
