XSeries 2 等离子体质谱仪形态分析应用-有机锡的分析

abstract:

There are two current EPA protocols for the determination of organotins; the first concerns the analysis of marine and fresh water by solid-liquid extraction and GC-ECD (Method 282.3) and the other uses microliquid chromatography coupled to electrospray iontrap mass spectrometry (Method 8323). The latter uses 1L sample volumes which are often inconvenient to manipulate. This application note describes the use of the GC-ICP-MS instrument package from Thermo Fisher Scientific to determine trace concentrations of butyltins in potable water and leachates from PVC tubing.
