摘要
介绍了P-E公司的预排/切割进样技术。大量溶剂可在进入毛细管柱前排出气相色谱系统,因而可以加大进样量以提高痕量分析的灵敏度。进样量最大可达150μL,检测限可下降1~2个数量级。给出了实际样品的分析结果。
The PreVent technique of Perkin-Elmer is described. Large quantities of solvent can be vented reaching capillary column, thus sample volume can be increased (up to 150μL) to enhance detection sensitivity in trace analysis. The detection limis can be lowered by 1~2 orders of magnitude. Practical results of sample analyses are given
