Calibration of the IR-detector for low sulfur concentrations

For the analysis of low sulfur contents with the IR detector a new calibration should be performed using a sulfanilic acid solution. Depending on the expected sulfur content, the concentration of the sulfanilic acid solution should be calculated by the user.

This Technical Note presents a custom calibration for the IR detector of the UNICUBE^®, vario EL cube, and vario MACRO cube for small sulfur concentrations using a sulfanilic acid solution.
