The OPAL-103 Triazine Analysis System is a compact form-factor triazine analysis instrument. The system is a portable, easy-to-use chemical analysis tool designed for the quantitative analysis of %-level, triazine-based H2S scavenger and biocide solutions. A two-minute test provides the triazine activity for either 5-45% or 30-80% triazine solutions. Software upgrades enable additional capabilities, including the quantification of excess monoethanolamine in fresh scavenger or the dithiazine content in spent scavenger solutions. The OPAL-103 Triazine Analysis System provides the benefit of laboratory-grade capabilities without the need for expensive, complex laboratory instruments and technical expertise.
