The important considerations of safety, convenience and cost savings influenced the design of the new nitrogen generator tailored for LC-MS analysers.
The generator is not hazardous and can be installed in the laboratory if required, although it is normally sited remotely with a nylon pipe feed (6 mm dia.) to the instrument.
The advanced technology developed by CLAIND produces pure nitrogen, allowing the N2 LCMS generator to supply any LC-MS produced by any manufacturer!
When compared to costs of bought-in nitrogen supplies the N2 LCMS should show a capital repayment time less than 16 months. Thereafter, the nitrogen is supplied virtually free of charge.
Independence is the main feature of these generators. They only require a supply of mains electricity for automatic, unattended operation. Pressing a button is the only operation to start up the generator, which operates automatically 24 hours a day, 365 days a year.
Maintenance is limited to changing a few filter elements taking less than 30 minutes per year. The system regenerates itself automatically giving you a continuous, uninterrupted supply of gas.
Working Principle:
Thanks to the PSA (Pressure Swing Adsorption) principle the generator produces nitrogen by compressing ambient air and passing it into a Carbon Molecular Sieve bed (CMS).
Inside the CMS bed, oxygen, moisture, CO2 and other 'contaminants' are trapped allowing nitrogen to pass through into a holding reservoir.
Nitrogen from the holding reservoir is regulated to a fixed flow and pressure before exiting the generator.
Models available:
N2 LC-MS 1: nitrogen generator with built in compressor
N2 LC-MS 0: nitrogen generator with external air supply (suggested in case of 2xLCMS or in case of APCI interface when higher flow is requested)
