msFineAnalysis iQ Ver.2 Target Analysis Example I Rapid Analysis of Food Aroma Components
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 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, similarity and retention index with the NIST database are confirmed on the detected peak. These results are used to determine whether or not it is the target compound. This time we report the results of the analysis of optional aromatic components from the volatile organic compounds of hamburger using this method.
