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.

Available in 2 models :
MAESTRO-TF / Maestro-TF-HF : The triple flow, specifically designed to supply Curtain, Source & Exhaust gases with dry air and nitrogen for ABI SCIEX LCMS instruments.

The generator is controlled using the latest in HMI touch screen technology to display the process in real time, inlet / outlet pressure, N2/Air Flow and status of the system.

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 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.
