Monitoring of Toxic Industrial Chemicals (TICs)

Rapid Monitoring of Dimethyl Sulfate (DMS) in Chemical Plants using GC-IMS Technology

Toxic industrial chemicals (TICs) or materials (TIMs) are substances that exhibit harmful effects on humans and are common in manufacturing facilities, chemical plants, maintenance areas or general storage areas. Exposure to those chemicals are seriously harmful especially after multiple low-level exposures. Dimethyl sulfate (DMS) is commonly used as a reagent for the methylation of phenoles, amines, and thiols. In industry DMS is preferred, compared to other methylating agents, because of its low cost and high reactivity. It is known that DMS is carcinogenic, mutagenic, highly poisonous, corrosive, environmentally hazardous and volatile. The substance can be absorbed through skin, mucous membranes, and gastrointestinal tract. With its GC-IMS device G.A.S. developed a highly selective and sensitive measuring system for rapid monitoring of Dimethyl Sulfate in chemical plants.
