ω-3 Arachidonic Acid Quant-PAK

The ω-3 arachidonic acid Quant-PAK has been designed for the convenient, precise quantification of ω-3 arachidonic acid by GC- or LC-MS. It includes a 50 µg vial of ω-3 arachidonic acid-d8 and a precisely weighed vial of unlabeled ω-3 arachidonic acid, with the precise weight (2-4 mg) indicated on the vial. This unlabeled ω-3 arachidonic acid can be used to quantify the ω-3 arachidonic acid-d8 standard by constructing a standard curve of peak intensity ratios (deuterated versus unlabeled).
