Integrated Analysis of High Resolution GC-MS Data Using Hard and Soft Ionization to Identify Trace Impurities

Brought to you by JEOL

Overview

Non-targeted analysis of complex mixtures by GC-HRMS should make use of all of the available data to identify unknowns. Herein, an automated data analysis software package combining chromatographic deconvolution with integrated analysis of high-resolution mass spectra for electron ionization (EI) and soft ionization measurements is applied to the identification of trace impurities in a fine chemical (triphenylphosphine).

Key Objectivesï¼š

Learn about how to use an automated data analysis software to identify trace impurities
How EI and soft ionization measurements successfully identify unknown trace impurities
Learn how to overcome problems arising from weak or absent molecular ions, which make it difficult to discriminate between compounds with different compositions, but similar mass spectra.
