As a first pass, a good approach to extracting information from a mass spectrum (MS) is to look for two things: intense peaks with a recognizable m/z and losses (or gains) between peaks. In LC mass spectra, one unknown impurity showing the mass of 83, parent peak showing mass of 83 and 234. Confounding Factors to Thyroglobulin Interpretation One potential methodology to get away from the TgAb interference problem is liquid chromatography-tandem mass spectrometry (LC-MS/MS). Comprehensive However, the improvement in information yields complex data requiring comprehensive analyses to interpret the rich information and to extract useful information for characterizing sample composition. In leave-one-out cross-validation, it outperforms popular techniques for classification of mass spectra, such as principal component analysis with discriminant function analysis, soft independent modeling of class analogy, and decision tree learning. The parent peak mass is 234 theoretical. Unlike other mass spectrometry texts, this comprehensive reference provides systematic descriptions of the various types of mass analysers and ionisation, along with corresponding strategies for interpretation of data. Mass spectral interpretation for chromatographers This material is designed to help GC/MS beginners who want to understand a few mass spectral interpretation basics.
