In Nov.2006, the program products “The calibration gases with micro-concentration and multi-components”, “The gas mixtures with micro-concentration sulphides in N2”, “High-purity NO gas” passed Dalian payoffs identifications. The techniques of these three kinds of products have achieved world’s top level according to the judgment of expert judges, and were awarded the second-class and third-class Progress Prize in science and technology in Mar. 2007.     
“The calibration gases with micro-concentration and multi-components” means we can prepare the hydrocarbon standard gas with more than twenty kinds of gas composition and the contents achieved ppm-level. It can be widely used in many fields of petroleum chemical industry, coal chemical industry and science researches.
“The gas mixtures with micro-concentration sulphides in N2” overcame the technical problems of adsorption and corrosivity with sulphides to prepare sulphides by ppb-level, such as hydrogen sulfide, carbon oxysulfide, sulfur dioxide, etc. The products we prepared are widely used in many fields of environmental monitoring, electronic industry and petroleum chemical industry.
The program of “High-purity NO gas” is a State Innovation Fund program, in which we successfully produced NO gas with 99.9% purity, which can be widely used as an urgent terminator in the production of PVC.
