Application of Gas Chromatography in Gas Component Analysis
Abstract: Chromatography has high sensitivity and selectivity, and has been widely used in the process industry. This article briefly describes the working principle and basic structure of gas chromatography, and introduces the working principles of TCD, FPD, and FID commonly used in gas chromatography. This article mainly introduces the application of gas chromatography for the specific working conditions of low-temperature methanol washing in a certain project.

Online analyzers are used for process automatic detection and have the function of continuously, reliably, and timely providing process quality information to operators or self-control devices. They are an important component of instruments and meters. There are various types of online analyzers that are suitable for different occasions. Chromatography has become a widely used component analyzer in the process industry due to its high sensitivity, accuracy, selectivity, and reliability.
