Zero Air HC Free

Compact HC free Pure Zero Air Generator from dot-red

The dot-red Pure Air Generator series produces laboratory grade purified air (Zero Air) in large quantities for the most accurate and convenient FID (Flame Ionization Detectors) and other detectors like FPD.

Designed with safety and convenience in mind, this system will generate HC (Hydrocarbon) free air eliminating the need for inconvenient high-pressure gas cylinders. The Pure Air Generator Series remove HC pollutants to less than 0.1 ppm, and all kind of particles. The typical flows are between 1.5 NL/min and 30 NL/min.

Operation of the generator requires low level of electrical power. This complete turnkey system is engineered with the highest quality components, is easy to install, and requires only minimal annual maintenance.

The dot-red Pure Air Generators do not require an external compressed air supply.

Working principle:

The internal pump will compress the ambient air. Once compressed, the air is cooled and dried by an automatic coalescent filter. Air is next channeled into a stainless steel catalyst chamber where any background hydrocarbons or carbon monoxide are oxidized. This chamber is filled with a highly efficient platinum catalyst, heated to very high temperatures to insure hydrocarbon removal to less than 0.1 ppm. The compressed is stored in an internal tank. A final high-grade filter is used to remove 99.99% of particulates greater than 0.5 microns in size. Then the air is regulated in pressure and ready to use. The compressor stops once the tank has reached its upper pressure level and starts again, once the tank has reached its lower pressure level.

The Pure Air Generator is mainly used to aliment the Flame of GC with hydrocarbon free Air (also known as Zero Air). By using the Pure Air Generator, the base line of the GC will be very low and stable, giving you the best possible accurate measurement. The Pure Air Generator can also be used to perform the Zero of Total Hydrocarbon Analysers.

Application of Pure Air:

° Flame Gas for GC-FID / GC-FPD / THC
° Zero Air for THC
