·Product Description
The headspace injection technique is a convenient and efficient method for sample preparation in gas chromatography. It is ideal for analyzing volatile components. The process involves placing the sample into a sealed container and heating it to allow volatile compounds to reach equilibrium between the liquid (or solid) phase and the gas phase. The top gas is then extracted and analyzed for the presence of volatile substances.
This method eliminates the need for complex sample preparation steps and avoids interference from organic solvents, reducing contamination at the gas chromatography inlet. The DK-300A is compatible with various gas chromatography systems both domestically and internationally.
·Features
1. Integrated sampling pump and valve ensure precise quantitative analysis with high sensitivity.
2. The sampling valve and transfer line can be temperature-controlled to prevent condensation of samples.
3. Anti-blow function on the sampling pipeline and valve prevents cross-contamination.
4. Excellent compatibility with a wide range of gas chromatography instruments worldwide.
5. Microcomputer control makes operation easy, with a membrane keyboard and synchronized data processing functionality.
