A HPLC method was developed to measure trimethylamine in fish oil supplements, to determine if the level of this compound affects product quality attributes such as rancidity.

A fast ultrahigh-pressure liquid chromatography (UHPLC) method, with low solvent consumption, is described for the determination of coenzyme Q10 in a variety of complex formulations. This method exhibits good linearity, reproducibility, accuracy, recovery, and specificity, while resulting in an acceptable limit of detection (LOD) and limit of quantification (LOQ).
