If your laboratory has one or more applications that demand a constant, high volume of laboratory gas you may be able to justify the cost (wish to consider the purchase of) of a laboratory gas generator which could save you money and make improvements to your productivity and laboratory safety at the same time.

Gas Generators can be used with any instrumentation requiring high purity hydrogen, nitrogen or zero air, anywhere a standard electrical supply is available.

Typical applications demanding constant high laboratory gas flows and where a laboratory gas generator may be justified include:

LC/MS instruments

Spectrometers

Sample prep

Auto samplers

ELSD
