Reasons for purchasing imported chromatographic columns

Repeatability and reliability. This instrument is mainly used for soil pesticide residues, indoor gas pollution and other samples of the detection of such organic compounds require a sui detector path (inlet, column, etc.), similar equipment in this regard is still not stable, can not guarantee the repeatability and reliability of the data of the relevant test items. Domestic equipment in the gas flow path control accuracy and sensitivity of the detector and imported equipment is still a big gap.
