Product Description
Gas Chromatography Mass Spectrometry machine adopts ceramic/platinum wire dual model heating. It mainly utilizes the differences in boiling point, polarity and adsorption coefficient of each component in the sample in the chromatographic column to separate the components in the chromatographic column, and conducts qualitative and quantitative analysis on the separated components.
