GC- QTOF Analysis
Gas chromatography time-of-flight mass spectrometry, which can eliminate Isobar interference with precise molecular weight and further structural analysis and identification.
Applications :
Semiconductor industry air quality : Process environment, Air filter performance, FOUP air quality ; Synthesis/manufacturing process outgassing ; Accurate molecular analysis and identification of unknowns

GC-MS Data : only from mass spectrometry

GC-QTOF : Accurate molecular to impurity identified
