The DHA oxylipin LC-MS mixture contains oxylipin metabolites derived from docosahexaenoic acid.

• Each vial contains a mixture of standards packaged in amber ampules purged with argon
• >1 ml provided at the concentration specified in the insert
• Designed for direct snap and inject use in mass spectrometry applications
• Ideally suited for method development and as a system suitability standard

The mixture is supplied in an amber ampule in which the headspace has been purged with argon to prevent lipid oxidation. This product has been designed for direct use in LC-MS applications. The solution may be used as a system suitability standard or tuning standard. After opening, we recommend that the mixture be transferred immediately to a 1 ml glass screw cap vial, to prevent solvent evaporation, and stored at -20°C. The mixture should be discarded after multiple freeze/thaw cycles. This mixture contains (±)4-HDHA (Item No. 33200), (±)7-HDHA (Item No. 33300), (±)8-HDHA (Item No. 33350), (±)10-HDHA (Item No. 33400), (±)11-HDHA (Item No. 33450), (±)13-HDHA (Item No. 33500), 14(S)-HDHA (Item No. 15253), (±)16-HDHA (Item No. 33600), 17(S)-HDHA (Item No. 10009799), and (±)20-HDHA (Item No. 33750).
