In this presentation, we will discuss a new, completely redesigned high-resolution time-of-flight mass spectrometer for GC-MS analysis that also includes integrated software that uses of all of the available information to identify compounds in complex mixtures. Specifically, this new GC-MS system features increased resolving power (R > 30,000) and high mass accuracy (< 1 ppm) while also offering a full complement of ionization techniques that include classical electron ionization (EI) and soft ionization (CI, PI, FI) along with combination EI/FI/FD and EI/PI ion sources.
Additionally, this new GC-MS system is equipped with data analysis software that uses high resolution MS in combination with EI and soft ionization methods to automatically generate a color-coded qualitative analysis report for all analytes present in the sample. The software workflow consists of chromatographic peak deconvolution followed by database matching, elemental composition determination for the molecular ion, isotope pattern matching, and EI fragment accurate mass analysis to identify the most likely candidates for compounds registered in the databases. This information can also help facilitate the identification of compounds that are not in the database. The latest version of the software includes a compare function that allows for the quick comparison of samples to identify their differences. Several examples will be presented to show the effectiveness of combining this new-high performance GC-MS with our latest version of automated qualitative analysis software.
