- ... Adulteration of vegetable oils to maximize profit is a worldwide problem. Atmospheric pressure chemical ionisation (APCI) and photoionisation (APPI) mass spectrometry methods were developed to detect the relative abundances of unsaturated fatty acids (FAs) present in vegetable oils with the objective of high throughput and rapid identification of adulteration. The ionisation efficiencies of both m ...
