CPI maintains and operates a used lubricant analysis laboratory. Analyses include kinematic viscosity, total acid number, moisture level, particle count, spectrochemical analysis, and liquid chromatography. Additional routine analytical capabilities include gas chromatography coupled with mass spectroscopy, Fourier-transform infra-red spectroscopy, high performance liquid phase chromatography, refrigerant/lubricant miscibility, materials compatibility and stability.
CPI's R&D facility is located in Midland, Michigan. Standard R&D, analytical and troubleshooting work is conducted at this facility. CPI also has a technical sales office in Cleveland, UK which is a focal point for technical/applications support in Europe.
