Purity assay of solvent samples (GC-FID and Karl Fischer)

Solvent purity assay with GC-FID and Karl Fischer techniques.

Determination is performed by analyzing the sample with GC-FID and comparing the area of the solvent signal to the combined area of all peaks. The concentration of the solvent in the sample is expressed as a percentage (%).

Karl Fischer titration is used to determine the amount of water in the sample.
