Tender description

Purchase of 1 gas chromatography high resolution accurate mass-mass spectrometer and 1 inductively coupled plasma mass spectrometer. The system is a high resolution accurate mass-mass spectrometer interfaced to a gas chromatography (GC) system to chromatographically separate the compounds of interest before identification in the mass spectrometer. The GC system needs to be capable of multidimensional chromatography (GC x GC) and the mass spectrometer should have a mass accuracy < 10 ppm and resolution > 5000. 1 system is required. The system is an automated inductively coupled plasma torch ion source with a quadrupole mass analyser and detection system. The system should include a cell, placed between the ion optics and the analyser quadrupole, into which gases can be introduced to remove polyatomic species from the ion beam before they enter the mass analyser. The system must be capable of performing major, minor, and trace (PPT to per cent) multi-elemental analysis in both aqueous and non-aqueous media with high accuracy and precision for routine and R&D applications.
