Minimizing Ammonia Gas Exposure with Movable Toxic Gas Purifier

Ammonium hydroxide is widely used across the semiconductor, metal, and pharmaceutical industries for pH control and surface cleaning,

but it readily vaporizes at room temperature to release a highly pungent ammonia gas.

Exposure to ammonia gas poses severe health risks, including respiratory distress, eye damage, and skin burns.

GT SCIEN offers a Movable Toxic Gas Purifier equipped with a specialized TOGA® filter designed to capture

ammonia gas directly at the source. As demonstrated in a case study with Company H during ammonium hydroxide bottle

replacement in a silicon wafer reprocessing line, GT SCIEN’s purifier dramatically reduced inlet concentrations of

up to 50 ppm down to under 1 ppm at the outlet, ensuring a safe and compliant working environment.
