Beschreibung

Allgemeine Beschreibung

α-Lipoic acid is an antioxidant which is generally present in plants, animals and many other microorganisms.

Anwendung

α-Lipoic acid has been used as a reference standard for the analysis of α-lipoic acid in human plasma by high performance liquid chromatography coupled to electron capture detector (HPLC-ECD), in various food matrices and dietary supplements by HPLC combined with coulometric electrode array detector (CEAD) as well as electrospray ionization mass spectrometer (ESI-MS).
It may be used as a reference standard for the determination of α-lipoic acid in human urine by isocratic reversed-phase HPLC and in α-lipoic acid capsules by HPLC with chemiluminescence detection.

Verpackung

Bottomless glass bottle. Contents are inside inserted fused cone.
