FDGSi PURAIR laboratory gas generators for mass spectrometery lc/ms, gc/ms, ms/ms - from krss


The PURAIR-34/1 DF has been designed specifically for systems which require a source of Dry Air (Nebulizer/Heating Gas) and Air (Exhaust Gas), such as Shimadzus LCMS-8080.

Pure Air is produced by using a cyclonic water separator filter, submicronic coalescing filter and membrane air dryer, removing moisture and other gases, delivering dry, clean, phthalate free air.

The generator provide two continuous streams of Pure 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 LCMS instruments make cylinder supply inappropriate for such applications. A constant, uninterrupted gas supply eliminates interruptions of analyses to change cylinders.

Improved economy
Pure Air gas produced as standard

Improved safety
Pure 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.
