Abstract
In this presentation, we will discuss a newly redesigned high-resolution time-of-flight mass spectrometer for GCxGC-HRMS analysis. This new HRMS features increased resolving power (R +30,000) and high mass accuracy (less than 1 ppm) while also offering a variety of ionization techniques that include electron ionization (EI) as standard with the system as well as three optional soft Ionization methods -- chemical ionization (CI), photoionization (PI), and field ionization (FI). Additionally, there are 2 combination ion sources (EI/FI/FD and EI/PI) that allow for switching between hard and soft ionization without breaking vacuum. Several applications will be presented to highlight the capabilities of this new-high performance HRMS when combined with GCxGC.
