Abstract

The invention relates to the analytical instrument filed in chemistry, which provides an air analyzer and comprises an air pressure transferring pump, an air pressure transferring tube, an automatic controller, a sample introduction measuring device and an air element adsorbing device. The air element adsorbing device comprises a plurality of air element adsorbing units with same structure, and the air element adsorbing units are connected with the sample introduction measuring device, the air pressure transferring tube and an automatic controller. The adsorbing bottles of each air element adsorbing bottle is loaded with adsorbing liquid for adsorbing different air or flammable air burning wire, which can be used in the air element analyzing of complicate component, the analyzing progress is controlled by automatic controlling procedure, the manufacture cost is low, the operation progress is simple and the analyzing result is accurate and reliable.

Description

technical field [0001] The invention relates to the field of analytical instruments in the specialty of analytical chemistry. Background technique [0002] Gas analyzers are used for gases that can be quantitatively absorbed by chemical absorption liquids or can be converted into quantitatively absorbed gases (such as CO 2 , O 2 , CO, H 2 、CH 4 , acetylene, etc.) analysis. It has broad application prospects in chemical industry, mining, metallurgy and modern agriculture. Industrial gas analysis chemical absorption relative chromatography has the advantages of price, site, no need for carrier gas, simplicity, etc., and is widely used. However, the current chemical absorption method also has the disadvantages of relatively cumbersome operation procedures, and difficulty in intelligent automation of absorption and measurement. Although there are patents on the automatic detection of the chemical absorption method at present, there are defects in automatic operation, and t...
