physicochemical characterization & analytical chemistry 

Charles River has vast experience conducting various physicochemical testing packages (or stand-alone tests) to assess the environmental impact and safety of chemicals. We offer a full range of physicochemical testing to meet all regulatory requirements, such as OECD, CIPAC, OPPTS and European Regulation No. 1907/2006 (REACH).

• Physical state
• Melting point
• Boiling point
• Relative density
• Surface tension
• Water solubility
• Organic solvent solubility
• Octanol/water partition coefficient
• Dissociation constant
• Flammability
• pH
• Viscosity
• Oxidizing or reducing properties
• Rate of hydrolysis (cold)
• Spectra (UV, UV/VB, IR, NMR, MS)

 
Analytical Capabilities

A suitable, validated analytical method is required to support many product chemistry and ecotoxicology tests. Experienced analysts are available to establish new analytical methods or to transfer existing methodology using a wide range of up-to-date equipment:

• HPLC (UV/visible, diode array, fluorescence, refractive index, light scattering, electrochemical)
• GC (FID, NPD, TCD, ECD, FPD)
• LC-MS, GC-MSD, LC-MS/MS, time of flight (QToF, IT-ToF)
• Capillary electrophoresis (diode array, UV/visible)
• Dionex ion chromatography (conductivity detection)
• ICP-OES (Optima 8000)
