Configuration List of 36 Components of Gas Chromatograph for Baijiu Methanol and Ethanol Detection

Yun TangConfiguration List of 36 Components of Gas Chromatograph for Baijiu Methanol and Ethanol DetectionIt is an instrument that uses chromatographic separation technology and detection technology to qualitatively and quantitatively analyze complex mixtures of multiple components. It is usually used to analyze organic compounds in soil that are thermally stable and have a boiling point not exceeding 500 ° C, such as volatile organic compounds, organochlorine, organophosphorus, polycyclic aromatic hydrocarbons, phthalates, etc.

According to the response principle of detectors, they can be divided into concentration type detectors and mass type detectors.

(1) Concentration type detector: measures the instantaneous changes in the concentration of components in the carrier gas, that is, the response value of the detector is proportional to the concentration of the components. Such as thermal conductivity detectors and electron capture detectors.

(2) Quality detector: measures the speed change of the sample carried in the carrier gas entering the detector, that is, the response signal of the detector is proportional to the mass of the components entering the detector per unit time. Such as hydrogen flame ionization detector and flame photometric detector.
