测定SCCPs最常用的方法是气相色谱-电子捕获负化学电离质谱法(GC-ECNI-MS)[1]。但针对该方法的分析条件优化报道并不多见,本文对色谱柱参数、GC-MS系统温度、质谱监测离子等分析条件进行了优化,得到SCCPs的仪器分析条件如下:使用Agilent 6890N-5975C型气质联用仪,配化学电离源和DB-5MS(15 m×0.25mm i.d.×...
GC-ECNI-MS法检测纺织品中氯化松节油 林金美 【期刊名称】《针织工业》 【年(卷),期】2024()1 【摘要】用气相色谱-电子捕获负化学离子源-质谱法(GC-ECNI-MS)对纺织品中的氯化松节油进行定性和定量分析。通过对分子离子峰和脱氯离子峰的加和与浓度之间的关系转化,实现对氯化松节油的定量分析。对纺织品常用棉...
A method for the quantification of the sum of short chain chlorinated paraffins (SCCPs) by GC–ECNI-MS was developed. This method is suited to the special demands of environmental sediment analysis using an approach of sum determination by multiple regression quantification and is independent of th...

酸碱硅胶柱层析法沉积物是富含硫,有机质及各种氯代烃的复杂介质,分析难度大,本方法针对最普及的GC-ECNI-MS测定法,对沉积物的分析方法学进行了优化,进一步降低了SCCPs定量的不确定性,以基质复杂的沉积物样品为研究对象,优化了样品净化和仪器分析条件,为SCCPs的定量提供尽可能高的准确性....
With this high carrier gas flow, the column residence time of BDE-209 was shortened by approximate to 25%, the peak height was increased and, consequently, the limit of detection by GC/ECNI-MS in selected ion monitoring (SIM) mode was improved. When this high-flow GC/ECNI-MS-SIM method...
