气相色谱仪检定规程
本规程适用于新制造、使用中和修理后的以热导(TCD)、火焰离子化(FID)、火焰光
度(FPD)、电子俘获(ECD),氮磷(NPD)为检测器的实验室通用气相色谱仪的检定。氢
离子化、氦离子化检测器可参照火焰离子化检测器的检定条件进行测试
概述
气相色谱仪(以下简称仪器)是利用试样中各组分，在色谱柱中的气相和固定相间的分
配及吸附系数不同，由载气把气体试样或汽化后的试样带人色谱柱中进行分离，并通过检测
器进行检测的仪器。根据各组分的保留时间和响应值进行定性、定量分析。
仪器由气路系统、进样系统、色谱柱、电气系统、检测系统、记录器或数据处理系统组
成
2 技术要求
2.1 技术指标
2.1.1 新制造仪器的柱箱温度稳定性、程序升温重复性、基线噪声、基线漂移、灵敏度或
检Nil限的检定均应符合其说明书的要求。
载气流速的稳定性、定量重复性、衰减器换档误差项目的检定，应符合本规程表1中的
技术指标。
