Sustainable Energy and Advanced Materials Laboratory
The Environmental and Particle Technology Laboratory at the Sustainable Energy and Advanced Materials Laboratory at Ohio University provides analytical support in characterizing physical properties of catalytic as well as other particles in term of porosity and particle size, analysis of combustive properties of various materials and mixtures, pH analysis, transmittance/absorbance analysis, and total carbon and organic carbon content of liquids.
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.
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
The oxygen bomb calorimeter shown above is manufactured by Parr Instrument Company. Oxygen bomb calorimeters are useful tools for determine the heat of combustion of compounds and materials.
The Quantachrom suface area analyzer shown above is used to determine the surface area and porosity of particles such as catalysts and powders.
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.
Spectronic 20 Colorimeter or "Spec 20" is a qualitative and quantitiave tool used to determine the absorbance and transmittance of various wavelengths light through prepared samples.
Manufacturer: Teledyne Tekmar
Instrument Model: TOC Torch
