Gas chromatography carries out the quantitative analysis and peculiar smell testing for residual solvent on food packaging cases after printing. It also tests the pureness and quality of organic solvents.
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.
