Cayman Chemical. convenient, precise quantification of linoleic acid by GC- or LC-MS. It includes a 50 µg vial of linoleic acid-d4 and a precisely weighed vial of unlabeled linoleic acid, with the precise weight (2-4 mg) indicated on the vial. This unlabeled linoleic acid can be used to quantify the linoleic.

The LC-MS/MS system used for determination and quantification of the analytes was a Vanquish ultra-high pressure liquid chromatograph (UHPLC, Aijiren Tech, San Jose, CA) coupled to a high-performance, ion funnel TSQ Altis ™ Triple Quadrupole Mass Spectrometer (Aijiren Tech, San Jose, CA). Analytes were separated with an Acclaim® Mixed-Mode
