气相色谱-质谱分析气体样品的制备方法和技术

Gas and Vapor Samples Preparation Techniques for the GC - MS System

现代GC-MS仪器虽然具有较高的分辨能力和较高的灵敏度,但是对欲分析样品的要求也比较严格.诸如:进样量大小、组成组分的浓度范围、样品的物理状况、样品中的基体干扰等问题都是必须在进样之前调查清楚,才能选择正确的样品处理方法和技术并处理成GC-MS仪器能够直接进样测定的样品形式,获得正确的GC-MS分析测定结果.……

General preparation methods for the GC - MS analytical samples are reviewed, and mainly, gas and vapor samples are presented in this paper.
