The VICI DBS ® PG Plus Rack combines the reliability of the hydrogen generator with a 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 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.

Utilizing the VICI DBS proprietary prepared field proven PEM (Proton Exchange Membrane) incorporated 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 along with 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 600 mL/min, one generator can supply up to 14 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, 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 (CSA and UL compliant).

Compressed air is prefiltered to 5 micron and 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 and stable baseline.

  • Zero Air Option Module

    The VICI DBS® Zero Air option is available for select hydrogen generator models. When adding this option the gas generator will additionally remove all costly and inconvenient gas cylinders of zero grade air. In addition to cost savings, instrument sensitivity is improved, cleaning requirements of detectors are reduced, lab safety is enhanced and potential for ghost peaks and baseline drift are reduced.
