MMA-Triazine is an important hydrogen sulfide scavenger used in the treatment of sour oil and gas. Conventional testing involves expensive, complicated laboratory methods that can take weeks to complete. With our simple, easy-to-use system for rapid analyte detection, it is possible to perform on-site, laboratory-grade testing for MMA-triazine in fresh and spent scavenger solutions. The reduction in testing time from weeks to minutes enables better decision making on when to replace scavenger solutions, improving scavenger system performance while reducing material and labor costs. When coupled with our dithiazine, MEA-triazine, and methylamine cartridges, the MMA-Triazine cartridge offers complete analysis of hydrogen sulfide scavenger solutions.
