RQ0000028716 3 Mass Spectrometers

Tender description

Purchase of 3 mass spectrometers to support testing of COLPRO equipment. Equipment will be used to analyse TICS and CW agents. These will include, but not be limited to: Hydrogen Cyanide, detection < 5 mg/m3 Cyanogen Chloride, detection < 5 mg/m3 DMMP, detection < ppb Chloropicrin, detection < 5 mg/m3 Acrylonitrile, detection < 4 mg/m3 Chlorine, detection < 1 mg/m3 Hydrogen sulphide, detection < 7 mg/m3 Hydrogen Chloride, detection < 2 mg/m3 Phosgene, detection < 0.08 mg/m3 Ammonia, detection < 18 mg/m3 Sulphur Dioxide, detection < 13.1 mg/m3 Ethylene Oxide, detection < 1.8 mg/m3 It is desirable to have ppb detection for all of the above. Mass Spectrometer Essential requirements: • 1-200 AMU range • Instrument PC controlled via rs232/Ethernet/USB or other physical cable connection (i.e. not wifi) • Triple filtered single quadrupole • Sub ppm resolution across all analytes of interest – to be supplied with ITT • Corrosion resistant internals - HCl is the particular corrosion problem but SO2, Cl2 and Phosgene are also problems for stainless steel. Hastelloy or similar alloy materials will be needed for exposed components. • Multi stream valve inlet to allow 3 or more inlets • Fast response, heated quartz inert capillary sample inlet - sufficient to display ‘real time’ detection • Heated transfer line(s) - up to 200 degrees to avoid condensation of vapours. For DMMP, we need to avoid condensation and run “cleaning/flushing” to clear contamination of the sample line. • PC software that can automatically output quantifiable results • PC software that can allow full calibration and easy data interpretation – generation of standard curves from calibrated gas samples e.g. Ethylene Oxide from which quantification of unknown samples can be made. • License for software to be installed on at least 3 different PCs (to cover the 3 Mass specs) • UK based, In-house engineering support with next day call out • Mass spectral database software to auto
