Premissa manufactures on-site arsine gas generators using a patented electrochemical process with refillable solid source canisters to produce ultra-pure arsine for compound semiconductors, solar cells, and LEDs. The generators eliminate the need for compressed arsine cylinders by generating arsine on demand and can provide blended arsine/hydrogen mixtures at specified pressures for MOCVD reactors.
