On-site Arsine Gas Generators

Premissa provides on-site, on-demand arsine (AsH3) gas generators for production of compound semiconductors, solar cells, and LEDs which eliminate the need and safety hazards of traditional compressed arsine cylinders. Premissa uses a unique, patented electrochemical process with a refillable solid source canister to electrochemically generate ultra-pure arsine at lower cost than compressed arsine cylinders. The generators can also automatically provide blended arsine/hydrogen mixtures, at the pressure needed, to your MOCVD reactor. The Premissa arsine generators eliminate the hazards to employees and community of compressed arsine gas cylinders at your Fab

No cylinder transportation to your plant
No cylinder storage
No cylinder change-outs

Premissa was founded to make production, distribution and handling of gases such as arsine and other toxic hydrides:

Faster. On demand, onsite, always available 24/7.
Better. Highest purity (>99.9999%) at lower cost than arsine gas cylinders–without the hazards. Fully automated production, simple graphic interface to chose arsine delivery time, concentration, and pressure for your MOCVD run.
Safer. No cylinders, cylinder delivery, changeouts or storage.
Efficient. Low energy consumption. Electrochemical process–instant ON/OFF.
Scalable. Pallet size canister modules; 5 slpm, with up to 50 kg arsine delivery per module (that’s equal to 20 to 50 arsine gas cylinders!)
Easier, Lower Cost. Refillable canisters designed for continuous operation, shipped by air-freight or truck

Based on over 25 years of prior experience with electrochemical industrial gas production, Premissa’s newly patented technology is the ONLY process providing industrial scale on-site arsine gas generation.
