overview

As a sample pretreatment system combined with gas chromatography system, it achieves the analysis of volatile organic compounds

characteristic

It can enrich and concentrate low concentration samples at ppb or ppt levels with fully automatic injection, and can process 24 samples at once. The injection method can be selected from Suma tank, adsorption tube or gas bag high-efficiency cold trap, with -20 ℃ low temperature capture and effective secondary focusing and 400 ℃ high temperature desorption to ensure the complete desorption of samples. The carrier gas flow rate can be accurately controlled, and it has airtightness self checking function. It is compatible with all adsorption tubes manufactured in accordance with international standards for full gas path anti adsorption treatment, and has full heating function to ensure no loss of samples. It can be perfectly compatible with multi brand gas chromatography systems and can be globally controlled through GHK control system.
