Gas chromatography is widely used in the chemical industry. The following are several applications in the chemical industry.

1. Analysis of Strontium, Phenanthrene, and Carbazole in Coking Products Anthraquinones, phenanthrenes, and carbazoles are important products in the coking industry. For example, phenanthrene and carbazole in the determination of pyrene are easily separated, while phenanthrene and pyrene are difficult to separate. Selenium, phenanthrene, and carbazole can be separated using a PEG20M modified CdCl2 column.

2. Determination of nitrochlorobenzene mesomeric isomers.

Nitrochlorobenzene is an important chemical raw material, and it is often necessary to determine a large amount of meta- and meta-isomeric minor impurities. The use of PEG 20M wool 3. Determination of the half-water gas component Semi-water gas analysis is essential in the nitrogen fertilizer industry In the analysis project, gas chromatography has been widely used in China to analyze the components of semi-water gas. The SP-2307 gas chromatograph is specifically designed not to analyze this mixed oxidation. This instrument uses two columns of 5A molecular sieves and carbon molecular sieves for analysis. O2, N2, CO, CH4 and CO2 gas components were measured at a column temperature of about 100°C. The 5A molecular sieve separates O2 and N2. Separation of O2+N2; CO, CH4 and CO2 at the same temperature using a carbon molecular sieve TDX-01. To prevent the poisoning of CO2 on the 5A molecular sieve column, some alkali asbestos should be installed before the column to absorb CO2. A TDX-01 column can also be used to separate the semi-water gas, except that the separation of O2 and N2 is less than ideal.

Multi-field chemical industry, professional analysis of gas chromatography, with different analytical operations for different analytes.
