UK-based equipment designer and manufacturer Peak Scientific has introduced two new nitrogen generators to the market, both essentially combining two separate gas systems in one unit.

The ABN2ZA and the AB-3G Nitrogen Generators are specifically designed to operate LCMS Instruments manufactured by Applied Biosystems/MDS Sciex.

The new products produce nitrogen and dry air through three independent outputs in the required flow rates, purities and pressures to cater for the requirements of all available Applied Biosystems/MDS Sciex LCMS Models, including the new API5500.

Each of the new models essentially combines two separate gas generator systems in one unit, with the source and exhaust gases (dry air) being generated by one system and the curtain gas (nitrogen) being generated by the other. The ABN2ZA and the AB-3G utilise proven gas technology that selectively removes oxygen, moisture and other gases to leave clean, dry, phthalate-free nitrogen and air.

Internal air compressors make the ABN2ZA a stand- alone, self-sufficient nitrogen generator, independent from external air sources, whereas the AB- 3G has been designed with additional compressor capacity. This additional capacity allows Peak Scientific to cycle the compressors more frequently, maximising compressor life.

In the unlikely event of one compressor failing, the internal control system will alert the user and manage the compressors to maintain a full output flow from the generator.

Peak Scientific has tested the new models extensively at its manufacturing plant and with end users around the world, ensuring reliability and longevity of the systems.

Applied Biosystems/MDS Sciex have further approved these products to supply nitrogen and dry air to all of their LCMS Applications.
