Waters GCT Premier
Waters GCT Premier is a high-resolution time-of-flight mass spectrometer. It is equipped with a gas chromatograph for GC/MS analysis using EI, positive CI or negative CI. Samples can also be introduced directly into the ionization source through a direct insertion probe or desorption chemical ionization (DCI) probe. Field desorption (FD), field ionization (FI) and liquid injection field desorption ionization (LIFDI) are also available for analyzing labile and air/moisture sensitive compounds.
