Decomposition of organic samples is done using the oxygen-flask combustion method (Schoniger application) or using the Anton Paar Microwave Induced Oxigen Combustion (MIC) for the and subsequent potentiometric titration by the 835 Titrando Metrohm  Titroprocessor and by Ion chromatography analysis  using a Dionex IC system.

Oxygen-Flask Combustion

MIC

CHN weight percentages are accurate and reproducible to within ± 0.3%, for a very pure sample. Halogens, S and P weight percentage are accurate and reproducible to within ± 0.5%.

Microbalance

Accurate weighing of samples is a prerequisite for organic elemental analysis since results are presented on a weight percent basis. A microbalance is an instrument capable of making precise measurements of weight of objects of relatively small mass: of the order of a million parts of a gram.

Determination of C, H, N and O is performed using the Thermo Flash 2000 CHN-O Elemental Analyzer. It uses a simultaneous flash combustion method (950-1060⁰C) for CHN and pyrolysis of oxygen to convert the sample elements to simple gases. The system uses a steady-state, wave front chromatographic approach to separate the controlled gases. They are detected as a function of their thermal conductivity. The analyzer uses a globally-recognized technique that is endorsed by official organizations worldwide. High speed microprocessor control, solid-state components and built-in diagnostics, provide assurance of performance fast, reliable, and accurate results for carbon, hydrogen, nitrogen, and oxygen detection.
