RQ0000028716 3 Mass Spectrometers DSTL

SUBJECT TO FUNDING

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 automatically identify unknown chemicals

• In-house customisation options to fit our needs - what capability has the supplier got to provide and support modified off the shelf items e.g. corrosion-resistant sample accessories?

• Not exceed 80x80x80cm in size

• Manufacturer suppled onsite training on delivery and set up of equipment at Dstl Porton Down

Desirable requirements

• 1-300 AMU range

• Detection of low ppm to high percentage concentrations of analytes in < 100 ms

• ≤5 ppb resolution for most analytes of interest

• Automated spectral analysis to give peak identification and composition analysis

• Manufacturer to provide on-site training package for a minimum of two Dstl staff upon installation of equipment

• Networkable comms to allow monitoring outside of lab (possibility to run equipment on virtual machines over network)

• Communications protocols which allow integration with other automated equipment in lab via Azeotech DAQ Factory

• Multi year support contract (>3 <5 years as part of the quote)

• Custom built trolley to allow MS to be sited under fume cupboards

• License for software to be installed on at least 6 different PCs (to cover the 3 Mass specs and 3 virtual networked machines)
