msFineAnalysis iQ Ver.2 Target Analysis Example II Rapid Analysis of Polymer additives
1. Introduction
Target Analysis is a method for fast and accurate search and evaluation of only the target compounds based on integrated qualitative analysis1) with Electron Ionization (EI) and Soft Ionization (SI) data. In this method, it is necessary to register the CAS RN®, molecular formula (or molecular weight), fragment composition formula of target compounds in the “Target List” in advance. Based on the registered information, each extracted ion chromatogram (EIC) is plotted for EI and SI measurement data, and peaks are detected. The molecular ion peak in the mass spectrum, its isotopic pattern, and the similarity and retention index with the NIST database are confirmed on the detected peak. Based on these results, it is determined whether it is the target compound or not. This time, we report the results of analyzing optional polymer additives from the pyrolysis measurement data of polyvinyl chloride (PVC) using this method.
