Trinder's reagent salicylate assay
WebThis salicylate-specific assay can be adapted for use with most discrete analyzers, for rapid emergency or routine testing with small serum or plasma sample volumes and a single calibration. The basis of this method is as follows: salicylate monooxygenase (EC 1.14.13.1) converts salicylate to catech … WebMay 1, 1983 · Abstract We describe a new automated method for measuring serum salicylate in the Multistat III microcentrifugal analyzer. Ferric nitrate reagent and serum blanking are used. We compare this new method, the automated Du Pont aca method, and the manual Trinder method with a "high-performance" liquid-chromatographic method. …
