DK-300A Headspace Injector
·Product description
The headspace injection technique is a convenient and efficient method for sample preparation in gas chromatography. It is particularly suitable for analyzing volatile components. The process involves placing the sample in a sealed container, heating it to reach equilibrium between the gas and liquid (or gas and solid) phases, and then extracting the gaseous phase for analysis. This method eliminates the need for complex sample pretreatment, reduces the risk of contamination from organic solvents, and minimizes pollutants entering the gas chromatography system. The DK-300A is compatible with all types of gas chromatographs both domestically and internationally.
·Features
1. Equipped with a sampling pump and valve, this system uses negative pressure sampling for precise and sensitive quantification.
2. The sampling valve and transfer line can be heated to prevent sample condensation.
3. Includes anti-blow function to prevent cross-contamination in the sampling pipeline and valve.
4. High compatibility with various gas chromatography systems worldwide.
5. Microcomputer-controlled with an easy-to-use membrane keyboard and synchronized data processing capabilities.
