Micromass® GCT Premier™ is Waters Newest Addition to its Line of Research-Grade Mass Spectrometers
Product News Jun 08, 2005
Waters have introduced a new bench-top gas chromatography mass spectrometer, the GCT Premier at ASMS, June 5 - 9, in San Antonio, TX. The GCT Premier is the newest member of the Micromass Premier time-of-flight mass spectrometers.
The GCT Premier couples gas chromatography with orthogonal acceleration time-of-flight mass spectrometry for the characterization of volatile compounds by way of exact mass and elemental composition determination.
Exact mass with elevated resolution leads to highly-conclusive quantitative and qualitative information for the structural elucidation of unknown compounds in a sample and in the confirmation of the identity and concentration of known compounds.
According to Waters, the benefits include higher throughput and better equipment utilization, easier data interpretation, improved selectivity and specificity, increased sensitivity, and a higher level of confidence in the results.
The instrument offers a variety of ionization options including electron impact ionization (EI), chemical ionization (CI), desorption chemical ionization (DCI), field ionization (FI), field desorption (FD) probe and solids probe.
Waters have said that there design engineers have made significant improvements in the spectral acquisition rate (20 scans/sec) of the instrument, double that of the company's previous model, and within the instrument's dynamic range (up to four orders of magnitude) vs. three orders.
The increased dynamic range of the GCT Premier with an instrument resolution of 7,000 FWHM, allows scientists to apply the advantages of elevated resolution and routine exact mass measurement to more complex sample types.
Under full MassLynx™ software control, the GCT Premier can be integrated with the Agilent® 6890N gas chromatograph and the Agilent 7683, GCPal™ and CombiPal™ autosamplers made by CTC® Analytics AG (Zwingen, Switzerland).
