UIC, Inc was established by Jerold Armstrong in 1965 as a manufacturer's representative firm and has grown into a full manufacturing and R&D facility. Currently, UIC is composed of two divisions: Instruments and Pumps. The Instrument Division manufactures coulometric carbon and sulfur analysis systems, vapor pressure and membrane osmometers, and kinematic/dynamic viscosity systems. UIC is also the exclusive US distributor for Cosmo automatic asphaltene analyzers. The Pumps Division operates under the Uniquest name and has been a division of UIC since the mid-1980s. The Pumps Division manufactures products for OEM applications for HPLC and GC manufacturers worldwide. Products and Markets The primary products for UIC are the coulometric carbon analysis systems. These systems are used extensively by the university, geological, oceanographic, petroleum and cleanliness verification markets. The carbon analysis systems have the ability to determine total carbon ( TC ), total organic carbon ( TOC ), total inorganic carbon ( TIC ) and surface carbon ( SC ) in solids, liquids, slurries and gases. The coulometric detection system operates on the principles of Faraday's Law and provides "calibration free" analysis of practically any material. Typical analysis times range from 5 to 8 minutes utilizing sample sizes from 10ug to 3g. The detection range for these systems is 10ug to 100mg of carbon per sample. This translates to an effective analytical range of 10ppm to 100% and will provide relative standard deviations below 0.2% when analyzing standard materials. The osmometers are used primarily in the university and polymer manufacturing markets as a way to determine average molecular weights of soluble polymers from 100 to 1, 000, 000 Dalton. The viscosity systems are used to determine kinematic viscosities of Newtonian fluids in the range of 0.3 to 100, 000 centistokes.
