The VICI DBS® HP Tower Zero produces nitrogen by utilizing a combination of filtration and pressure swing adsorption (PSA) technology. Standard compressed air is filtered by high-efficiency coalescing filters to remove all contaminants down to 5 µm. For ultra-sensitive applications such as GC carrier and make-up gas, units also include the additional heated catalyst module to ensure hydrocarbons are removed to <0.1 ppm. The air then passes through two columns filled with a proprietary blended carbon molecular sieve (CMS) which adsorbs O2, CO2, and moisture. These are desorbed to the atmosphere during the pressure swing cycle leaving a supply of ultra-pure nitrogen.

INCREASE EFFICIENCY

A constant gas supply with a guaranteed purity, eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

IMPROVE SAFETY

Nitrogen produced at low pressure and ambient temperature, removes the need for high-pressure cylinders.

RETURN ON INVESTMENT

The payback period can be as short as 6 to 12 months.

ENHANCE PERFORMANCE

Gas generators can be installed in the laboratory close to the instrument, eliminating the need for long gas lines from external cylinder supplies. A constant guaranteed high purity gas supply improves stability and ensures greater reproducibility of results.
