DK-300A Semi-Automatic Headspace Injector
·Product Description
Headspace injection is a convenient and efficient sample preparation technique used in gas chromatography. It is particularly suitable for analyzing volatile components. The process involves placing the sample into a sealed container, heating it to allow the volatile compounds to reach equilibrium between the liquid or solid phase and the headspace gas. Afterward, the top gas is extracted for analysis, eliminating the need for complex solvent-based extraction methods.
This method avoids the use of organic solvents, reducing contamination risks and improving the accuracy of results. It also minimizes the risk of pollution at the gas chromatography injection port, making it highly compatible with various gas chromatography systems both domestically and internationally.
·Features
1. Integrated sampling pump and valve system for negative pressure sampling, ensuring precise quantification and high sensitivity.
2. Temperature control for the sampling valve and transfer line to prevent condensation and maintain sample integrity.
3. Anti-blow function on the sampling pipeline and valve to prevent cross-contamination and ensure accurate results.
4. Excellent compatibility with all types of gas chromatography systems, both in China and abroad.
5. Microcomputer-controlled operation with a membrane keyboard, offering user-friendly interface and synchronized data processing capabilities.
