High-performance liquid chromatography degradation samples

The chemical properties of HVA, 5HIAA and 3-MD make them amenable to reverse-phase high-performance liquid chromatography (HPLC) with electrochemical detection. Furthermore, the composition of CSF means that little, if any, sample preparation is required prior to analysis. However, the susceptibility of these metabolites to oxidation means that careful sample collection and storage is required in order to minimise analyte degradation. [Pg.704]

The preferred blood sample is one collected with either K or Na salts of ethylenediaminetetraacetic acid (EDTA) as the anticoagulant. To minimize the formation of degradation products, which are especially noticeable as small bands eluting with similar retention time as Hb Ai and Hb F on high-performance liquid chromatography (HPLC) analysis, testing should be performed within 5 days of collection and samples should be stored at 4 "C. [Pg.1171]

Degradation samples are analyzed at the initial phases of high-performance liquid chromatography (HPLC) method development using... [Pg.97]
