1-2 Instrument Description
Introduction
The GCT Premier is a high-performance, bench-top, orthogonal
acceleration/time-of-flight (oa-TOF) mass spectrometer. To identify volatile
sample components, the instrument is coupled to a gas chromatograph (GC).
To identify nonvolatile components, it operates as a standalone instrument
that receives sample through a direct insertion (DI) or direct chemical
ionization (DCI) probe.
GCT Premier mass spectrometer:
Unlike scanning instruments, a TOF instrument performs parallel detection
of all masses within the spectrum at high sensitivity and acquisition rates.
This is particularly advantageous when the instrument is coupled to fast
chromatography, because each spectrum represents the sample composition
