气相色谱自出现以来一直受到业内人士的广泛关注,发展至今,其技术已经比较成熟,而且应用领域较广,目前被广泛应用在空气质量的检测中,现已成为苯含量检测的主要手段。气相色谱法概述通常认为气相色谱是一种柱色谱,依据所使用的色谱柱的粗细程度可将其分为一般的填充柱和毛细管柱。填充柱是指在对管道内径进行严格控制的前提下(管道内径控制在2-6mm),把固定相放在一个玻璃或者金属管道内,气体在管道内部发生变化, Since the advent of gas chromatography has been widespread concern in the industry, the development so far, the technology has been more mature, and a wide range of applications, is now widely used in air quality testing, has now become the main means of detection of benzene content. Overview of Gas Chromatography Gas Chromatography is generally considered a type of column chromatography that can be divided into general packed columns and capillary columns depending on the thickness of the column being used. Packed column refers to the premise of strict control of the pipe diameter (pipe diameter control in 2-6mm), the stationary phase on a glass or metal pipe, the gas inside the pipe changes,
