In a chromatography system, a device that quantitatively delivers an analytical sample to a column.
The liquid chromatograph has a diaphragm inlet syringe stop injection and a six-port injection valve injection.
Gas chromatography has a vaporization chamber and injection valve injection. Open-column gas chromatography has split injection and splitless injection. The injection valve is divided into manual and automatic.
The principle is that the sample to be tested is placed in a closed container, and the volatile component is volatilized from the sample matrix by heating, and the equilibrium is achieved in the gas-liquid (or gas-solid) phase, and the top gas is directly extracted for chromatography. Analyze to verify the composition and content of volatile components in the sample.
