JEOL MASS SPECTROMETER

MODEL JMS-T2000GC AccuTOF ^TM GCX

Ultimate GC-MS for challenging qualitative analyses (and quantitative analyses)

» High speed: 50 spectra/second

• » Compatible with Fast GC for high throughput analyses
  
• » Compatible with GCxGC for highly complex mixtures

» High resolution: 30,000 (FWHM) @ m/z 617

• » Highly selective quantitative analyses

» High mass accuracy: 1 ppm

• » Identification of unknowns by means of accurate mass measurements and elemental composition determinations

»Electron Ionization / Field Ionization (EI/FI) ion source (option)

• » FI: an old technique but still the only true soft ionization method for non-polar volatile analytes


• » EI/FI ion source allows instantaneous switching between EI (hard ionization for structural analysis) and FI (soft ionization method for molecular weight determination.)

Sample pre-processing options before GC

»Multi-shot pyrolyzer (Frontier Lab. Ltd.)

• » Pyrolysis products of newly developed materials (e.g., polymers) are mostly unknowns.
• » Accurate mass measurements and soft ionization (FI) can help identifying such unknowns.

Variety of non-GC sample inlets

» Direct Insertion Probe (DIP: option)

• » Conventional glass crucible design for solid samples

» Direct Exposure Probe (DEP: option)

• » Platinum filament for high-boiling point samples

» Field Desorption (FD: option)

• » Soft ionization method for non-polar non-volatile analytes up to 6,000 Da (and beyond)
• • » Synthetic polymers (oligomers)
  • » Petrochemical products
