Description

The University has a requirement to purchase an Orbitrap Gas Chromatograph Mass Spectrometer (GC-MS) with liquid, headspace and SPME arrow sample introduction systems. The instrument will be situated in the geography laboratories and will support researchers in multiple departments. The University has published this VEAT notice and intends to award a contract to Themo Fisher Scientific, following the expiry of 10 days from the date of publication of this notice.

Total Quantity or Scope

The University has a requirement to purchase a high-resolution accurate mass Orbitrap Gas Chromatograph Mass Spectrometer (GC-MS) with liquid, headspace and SPME arrow sample introduction systems. The Orbitrap GCMS must have the capability for highly accurate and reproducible identification, quantification, and tracing of individual organic compounds with known sources or pathways, from a wide variety of environments and sample types. The instrument must be supplied with computer hardware and software capable of operating the instrument and data processing/analysis. The University has published this VEAT notice and intends to award a contract to Thermo Fisher Scientific, following the expiry of 10 days from the date of publication of this notice.

Award Detail

CPV Codes

• 38432210 - Gas chromatographs
• 38433100 - Mass spectrometer

Legal Justification

The system must have the following key features: • A 60,000 resolution (Full Width Half Max m/z 200) system, capable of switching dynamically between full scan and Selected Ion Mode (SIM) mode. • Mass range of m/z 30 - 2000. • High sensitivity due to the low concentration of target molecules in environmental samples. Electron Ionisation: 100 fg octafluoronaphthalene on column, scanning m/z 50-300, S/N 10,000:1 Electron Ionisation Instrument Detection Limit: 6 fg octafluoronaphthalene derived at the 99% confidence level Positive Chemical Ionisation: 10 pg benzophenone on column, scanning m/z 80-230, S/N 150:1 • Vent free analytical column and ion source/lens exchange. • Variable electron energy acquisition for increased molecular ion production. • High mass accuracy below 2 ppm. • A bench top system with a height of no more than 1000 mm. • An interchangeable integrated sample introduction system (liquid, headspace and SPME arrow). • Fast MS/MS scan speeds (e.g. 7.5 Hz at 60,000), to allow for high throughput sample analyses. • Software capable of performing targeted and non-targeted analysis of complex environmental samples. • MS/MS and chemical ionisation for confirmation of molecular ion. • Compatibility with existing software systems (Chromeleon). • Compatibility with existing Thermo Scientific GC / GCMS systems to allow interchange of injector modules and parts (e.g. Programable Temperature Vaporisation, split/splitless, ion volumes)
