Ultra high-purity nitrogen generator HP Zero 1000 HC

for chromatographyPSACMS

Description
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.

Advantages

• Constant gas supply with guaranteed purity, eliminating interruptions to change cylinders and reducing instrument re-calibrations.
• Nitrogen produced at low pressure and ambient temperature removes the need for high-pressure cylinders.
• Payback period can be as short as 6 to 12 months.
• Can be installed close to instruments to eliminate long gas lines, improving stability and reproducibility of results.

Features

• Produces a continuous supply of high purity nitrogen
• On-demand supply 24/7
• Flow rate: 200 to 4000 mL/min (model dependent)
• Purity: up to >99.999% and hydrocarbon (THC) <0.1 ppm
• Outlet pressure: up to 5 barg (75 psig)
• Proprietary carbon molecular sieve technology (CMS)
• 2-year complete product warranty
• Easy to install, operate and maintain

Benefits

• Eliminates dangerous high-pressure cylinders improving workplace safety
• Removes logistics, downtime and costs associated with cylinder systems
• Flow capacity available to match specific instrument demands
• Ideal for all GC applications – stable baseline with increased sensitivity and repeatability
• Meets and exceeds requirements for demanding GC applications
• Superior air purification with long life catalyst technology
• Improves laboratory workflow and productivity
