Centri GCxGC-TOF-MS system

Description

For the purchase of Centri GCxGC-TOF-MS system for the discovery, profiling, and screening of volatile organic compounds. This equipment has been selected for the ability to allow automated HiSorb immersive extraction. Samples can be stacked and run in sequence, with detachment of probes from the robot arm allowing for the next sample extraction to begin. The robot then recollects the probe and inserts into the platform. The system allows for any injected samples to be recollected onto thermal desorption tubes, facilitating multiple analyses of the same extract. The mass spectrometer features tandem ionisation capability, which allows for generation of mass spectra profiles at two different ionisation energies simultaneously. This allows for increased confidence in compound identification and facilitates structural elucidation and isotope ratios. The entire platform is operated with ChromSpace software, allowing for integrated control of Centri automated extraction, GC injection, flow modulation, flame ionisation detection quantification, mass spectrometer operation, data processing, and statistical analysis. The University has published this VEAT notice and intends to award a contract to Markes International Analytical Limited, following the expiry of 10 full calendar days after the expiry of this notice.
