Beskrivelse
The Department of Animal and Veterinary Sciences, Aarhus University working with biomarkers for health, metabolic and nutritional status in farm and companion animals. Increasing focus on non-invasive methods in animal science increases the demand for analytical techniques dedicated to urine metabolomics and to this end the Department intends to buy a CE/MC. Especially bovine urine poses analytical challenges, and the purchase will have to meet several criteria enabling longitudinal studies on urine and other biofluids from multiple animal species. Robustness is mandatory in longitudinal studies, and is challenged in complex matrices like bovine urine. The CE/MS must enable large versatility (operation in different modes), high selectivity, and high throughput (short run times). The analytical platform must enable analysis of carbohydrates, amino acids, peptides, proteins, organic acids, and lipids (e.g. steroids) in complex matrices.

Beskrivelser af tildelingskriterier

  • Specific requirements: 1. To ensure effective communication and support from supplier the CE/MS must be a single-vendor solution for best possible support, ease-of-use, robustness, reliability and full software compatibility for CE, HPLC and MS. 2. To ensure and facilitate long time stability and reliable operation, for the use of a wide range of buffers and operating conditions, the interface must be designed with a coaxial solvent sheath flow or triple tube CE/MS interface. The interface design and use of sheath liquid acts essentially as the outlet buffer for the CE and maintains a spray independent of the magnitude of the flow rate or electro-osmotic flow (EOF). 3. To allow for greatest flexibility and control when working with negative as well as positively charged compounds the nebulizer in the CE-MS interface must operate at ground potential, which decouple the CE separation conditions from the MS operation conditions. 4. The CE-MS system must be flexible and use a standard ESI flow system to allow for robust and easy connectivity with an LCMS system and allowing direct switching between UHPLC, HPLC and CE flows and connections. 5. To identify analytes in complex matrices it is important that the MS has a high mass accuracy, and MS must have mass accuracy of <2 ppm RMS (negative) and <2 ppm RMS (positive). 6. Quadrupole isolation mass range m/z 20-4,000 and TOF range of m/z 20-10,000. 7. For long term stability of analyses the CE-MS nebulizer MUST enable large droplets and neutral mobile phase additives to pass by the MS inlet capillary minimizing contamination of the inlet. 8. To prevent MS contamination from large droplets and neutral mobile phase additives passing into the MS the CE-MS sprayer MUST be spraying orthogonal, at 90 degrees, to the MS source opening. 9. To ensure durability the temperature in the capillary cassette MUST be controlled and must be air cooled.
