DK-3001AMain features of the semi-automatic headspace sampler
Uniformly distributed sample heating positions reduce temperature gradients between different pore positions and improve the stability of analysis results.
The sampling pipeline and injection valve have a blowback function to prevent cross contamination between samples;
The quantitative loop of the injection valve and the controllable temperature of the sample transmission line are used to avoid condensation of the sample during transmission
The sampling pump and injection valve are combined for negative pressure sampling, without the influence of external gas additives, and have high sensitivity;
Equipped with over temperature and power-off protection for safer use;
The injection needle can be freely replaced, making it convenient to connect various models of GC at home and abroad
