Our CE Instruments Flash EA2000 offers percentage-level measurement of C, H, N and S using the combustion method. Oxygen analysis by the pyrolysis method is also possible using a second reactor column fitted to the instrument.
For SPEME researchers with a small number of samples, we offer a CHNS analysis service on a monthly basis. Please see the relevant web page for more details on how to use this service.
For samples with a low nitrogen content (ppm-0.5wt %) we can now offer analysis using our Analytik Jena Multi EA 5000 combustion analyser, which is equipped with a high-sensitivity chemiluminescent detector.
Our CE Instruments Flash EA2000 can be used in conjunction with a flame photometric detector, which enables us to offer ppm-level determinations of sulphur (only) in combustible samples.
The recent purchase of a Perkin Elmer Elan DRCe ICP/MS allows the determination of major and trace metals and other elements at ppb-ppt levels. A specialist extra sample introduction kit may be used to determine the metals present in organic liquids directly. The instrument can be run in full quantitative mode for more precise analysis of a small number of elements, or in total quantitative mode for the determination of a large number of elements.
Total Organic Carbon (TOC) and Total Inorganic Carbon (TIC) Analyser
The TOC and TIC of water and effluent samples can be measured using a Hach-Lange IL550 analyser. Both differential and NPOC methods are available.
