The VICI DBS® PG Plus FID Tower combines the reliability of the hydrogen generator with a zero air generator into one compact package. The FID Tower can be installed next to the GC and it’s small size preserves valuable bench space. This simple but effective instrument can supply all your FID detector grade 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 remote networking and cascading for built in redundancy.

With a maximum output capacity of 600 mL/min, one generator can supply up to 14 GCs. 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 GC.

A sophisticated control system connected to an easy to use touch screen control continuously monitors the vital operating parameters to ensure 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, MET (UL and CSA compliant).

Compressed air is prefiltered and then purified using a state of the art combined heated catalyst module. The zero grade air is free from total hydrocarbons to <0.1 ppm, making it ideal for all FID applications. These levels assure a low signal to noise ratio, ensuring a flat and stable baseline.
