FDGSi MAESTRO-DF/EVOQ-TQ laboratory gas generators for mass spectrometery lc/ms, gc/ms, ms/ms - from krss


LC-MS analysers do not all share the same requirements in terms of flow rate, pressure and purity of the gases needed for their operation.

MAESTRO-DF/EVOQ-TQ : The dual flow generator has been specifically designed to meet the nitrogen and dry air needs to supply the Bruker EVOQ triple quadrupole Mass Spectrometer.

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
Clean dry air and nitrogen gas produced as standard

Improved safety
Clean dry air and nitrogen gas produced at low pressure and ambient temperature removes the need for high pressure cylinders.

Security of supply

Integral oil free air compressor 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.
