NM Plus Rack Hydrogen Generator
The VICI DBS® NM Plus Rack instrument combines the reliability of the hydrogen generator with an optional zero air generator into a 19" rack. The generator can be installed in any suitable 19" static or mobile cabinet. This simple but effective instrument can supply all your FID gas and carrier gas requirements. Designed as a hazard-free alternative to high-pressure cylinders, all that is required is deionized water, compressed air and a standard electrical supply for weeks of continuous operation.
Overview
Hydrogen and zero air in a 19" rack.
Utilizing our proprietary Proton Exchange Membrane (PEM) inside a 100 % titanium cell provides superior generator performance and cell life. The unique high-pressure permeation membrane drying system eliminates the requirement for desiccant cartridges and the associated downtime and cost. Innovative software control allows unrivaled operational performance and safety as well as the additional options of auto water feed, remote networking and cascading for built-in redundancy.
With a maximum output capacity of 1350 mL/min, one generator can supply up to 33 FIDs. The compact design allows the generator to be installed directly in the laboratory, eliminating the requirement for long gas lines and guaranteeing the delivery of high-purity gas to your instrument.
A sophisticated control system connected to an easy-to-use touch screen continuously monitors vital operating parameters to ensure a safe and consistent performance. Built-in sensors will shut the generator down if internal/external leaks are present, or in case of contaminated water, low water or over pressure. This is why the VICI DBS generators meet the strict safety guidelines to be certified for CE, FCC and MET (UL and CSA compliant).
Compressed air is prefiltered, then purified using a state-of-the-art combined heated catalyst module. The resultant air is free from total hydrocarbons to <0.1 ppm, making it ideal for all FID applications. These levels guarantee a low signal-to-noise ratio, ensuring a flat, stable baseline.
