The THYSTER-DF/PEGA dual flow generator has been specifically designed to meet the nitrogen and pure air needs to supply a LECO PEGASUS 4D GC x GC-TOFMS

Nitrogen is produced by pressure swing absorption (PSA) to remove oxygen, carbon dioxide and water from compressed air and purified air is produced by using a cyclonic water separator filter and submicronic coalescing filter.

The generators provide two continuous streams of Nitrogen and Air from a single plug & play unit. The model is available with an integral oil free compressor, and is extremely quiet in operation.

The Generator is controlled using the latest in HMI touch screen technology to display the process in real time, inlet/outlet pressures.

Improve laboratory efficiency
The relatively high gas volumes required by the instrument make cylinder supply inappropriate for such applications. A constant, uninterrupted gas supply eliminates interruptions of analyses to change cylinders.

Improved economy
Pure Nitrogen/Air gas produced as standard

Improved safety
Nitrogen/Air produced at low pressure and ambient temperature removes the need for high pressure cylinders.

Security of supply
Integral oil free air compressor as an option guarantees continuous gas supply, independent of in house compressed air supply.

Simple installation
Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere.
