High Temperature Total Organic Carbon Analyzer

The Dohrmann High Tempterature Total Organic Carbon (TOC) Analyzer, DC-190, shown above can analyze a wide range of samples including those which are dirty, salty, or particulate-laden. The TOC can analyze liquids for total carbon, total organic carbon, inorganic carbon, non-purgeable organic carbon, and purgeable organic carbon with a detection range of 0.2 ppm to 50,000 ppm of carbon. The TOC can be used for waste water process control, analysis of potential hydrocarbon contamination in liquids, ethanol content in water, reactor effluent hydrocarbon and coke content, and a myriad of other uses.

Coulter Multisizer

The Coulter Multisizer is used to measure particle size and particle size distribution. For analysis particulates need to be suspended in a compatible solution, if not already. Multisizers can quantify particle size distribution for a wide range of particles ranging from red blood cells to fine mesh grit. The Coulter Multisizer shown above is used to measure catalyst particle size distribution and polymer particle size distribution among its variety of uses

Titrimeter

The Fisher Chlorine Titrimeter shown above is used to make quantitative measurements of residual chlorine in aqueous solutions. The titrimeter is used as one of the principle instruments for measuring chlorine dioxide concentrations in optimizing chlorine dioxide production techniques in the patented Chlorine Dioxide Technology developed by Dr. Lee and his group. In addition the titrimeter can be used for detecting chlorine concentrations in domestic water supplies as well as waste water discharge as a part of municpal and industrial waste water treatment.
