Elemental analysis

DB Lab is performing elemental analysis of carbon, hydrogen, nitrogen, and sulphur (CHNS). The analysis is performed as a double determination and under the GMP quality system.

The principle in elemental analysis (for CHNS) is cusbustion of the sample at elevated temperatures (900-1060 °C) under controlled supply of oxygen. During the combustion, carbon, hydrogen, nitrogen and sulfur are converted to CO2, H2O, N2 og SO2, respectively. These gasses passes through a cupper catalysts, after which they are detected by gas chromatography.
