For the Organic Biogeochemistry unit within the Department of Marine Microbiology and Biogeochemistry at the Royal Netherlands Institute for Sea Research (Texel) we intend to purchase a bench top high resolution mass spectrometer for the purpose of position specific stable isotope analysis (PSIA) of biomarker molecules. We intent to purchase a Q Exactive plus Orbitrap mass spectrometer, with enhanced resolution mode providing the following capabilities:
- Maximum resolution of 280,000 ppm (@ m/z 200) with routine mass accuracy of less than 3 ppm without use of lock mass
- Mass range 50 to 6000 m/z
- Quadrupole precursor isolation range down to 0.4 amu
- Collision induced dissociation MS2
- Heated Electrospray ionization (HESI)
- Atmospheric pressure chemical ionization (APCI)
- Syringe pump
