High-Resolution GC-MS for analysis of small volatile organics. Samples can be introduced via GC column or direct insertion probe (DIP). The system has both electron impact (EI), a hard ionization source, and chemical ionization (CI), a soft ionization source, capabilities.
Solid phase microextraction (SPME) or headspace sampling (HS) coupled with GC-MS is available upon consultation.
Standard applications
- High resolution accurate mass of volatile compounds
- Complex volatile GC-MS sample analysis
- Targeted, semi-targeted, or untargeted metabolomic GC-MS
- Fatty Acid Methyl Esterification (FAME) lipidomic GC-MS
