DW-EXPEC236 full-automatic headspace sampler is a pretreatment device that puts the sample to be tested in a sealed constant temperature system for gas-liquid or gas-solid balance, and sends the balanced components to be tested to chromatographic analysis. Based on the new design of static headspace pressurization technology, it realizes the solvent-free and efficient extraction of liquid samples and solid samples.

Gas Chromatography is a kind of instrument for qualitative and quantitative analysis of multicomponent complex mixture by using chromatographic separation technology and detection technology. Generally, it can be used to analyze the thermal stable organic compounds in soil, such as volatile organic compounds, organic chlorine, organic phosphorus, polycyclic aromatic hydrocarbons, phthalates, etc.

Liquid Chromatography uses the mixture in liquid-solid or immiscible between the two liquid distribution ratio differences, the mix of the first separation, then analysis and identification of the instrument.
