Model DK3001 Headspace Sampler can connect all types of GC instruments both at home and abroad, and it is an ideal sampling injection device, which transmits the volatile ingredients of the liquid or solid samplers into GC to conduct the separation and testing. Using headspace technology can avoid the complicated pre-sampling processes, avoid the interference to the analysis from organic solvent, and reduce the pollution to the chromatography column and injection port; With its advantages such as practicable and easy to operate, it is widely applied in the fields such as environment inspection (e.g. the detection of volatile halogenated hydrocarbon in drinking water, and volatile organic substances in industrial sewage), the detection of organic remaining solvent in medicament, and analysis on food, medical jurisprudence, petroleum and chemical engineering, packing material, paint, and wine industry.
