气相色谱仪的主要组成部分有5个,分别是载气系统、进样系统、分离系统、检测系统和记录系统,只有对其各个系统进行合理的维护和保养,才能延长仪器使用寿命,最大限度地降低仪器故障率,获得良好的色谱分离效果,确保测定结果的准确。其中,载气系统、进样系统和分离系统是影响气相色谱仪分析结果的关键,笔者结合自身多年使用气相色谱仪的实践经验,对气相色谱仪的载气系统、进样系统和分离系统的维护保养、使用注意事项进行了介绍,以供参考。
The main components of the gas chromatograph are five, namely the carrier gas system, injection system, separation system, detection system and recording system, and only its reasonable maintenance and maintenance of various systems in order to extend the life of the instrument, the maximum limit To reduce the failure rate of the instrument, get a good chromatographic separation, to ensure the accuracy of measurement results. Among them, the carrier gas system, injection system and separation system are the key to the GC analysis results. Based on the years of practical experience of gas chromatography, the author of the gas chromatograph carrier gas system, injection system and separation system Maintenance, the use of precautions were introduced for reference.
