This type of evaluation outline is applicable to the type evaluation of a gas chromatograph with a classification code of 46220500.

2 reference files

This outline refers to the following documents. JJG700 gas chromatograph verification procedure Standard column for GB/T 30430 gas chromatograph test For dated references, only dated versions apply to this specification; undated quotations The latest version (including all amendments) applies to this specification.

3 Overview

Gas Chromatograph (hereinafter referred to as the instrument) is to use the components in the sample in the gas phase and the stationary phase of the column. The distribution or adsorption coefficient is different, and the gas sample or the vaporized sample is carried into the column by the carrier gas to separate and pass An instrument that passes the detector for detection. According to the retention time and response value (peak area or peak height) of each component Sexual and quantitative analysis. Common detectors for the instrument are. thermal conductivity detector (TCD), flame ionization detector (FID), electron capture Detector (ECD), Flame Photometric Detector (FPD) and Nitrogen Phosphorus Detector (NPD). The instrument consists of a pneumatic system, a sampling system, a separation system, a temperature control system, a detection system, and a data processing system. composition. Key components that affect the metering performance of the instrument include. micro-current amplifier boards, flow controllers, temperature sensors, Detector.
