Product Details

GC-9801 Lab Gas Chromatograph

Application

To test the smell and solvent residues of printed packaging materials; test the quality and purity of the solvent.

Reaching the standards:

GB/T10004-2008, YBB00132002

Working principle :

Sample of gas, liquid or solid is processed and passes through vaporizing chamber, brought to chromatographic column separation system. Carried by nitrogen, the sample mixture passes and contacts the chromatographic column, and the composition components of the mixture are separated by chromatographic column. Then every separated component is brought to the detector system, and transformed by the detector to equivalent electronic signal, which is collected and recorded as data, so as to make qualitative and quantitative analysis of the components of the sample mixture.
