WebAbstract. We recently described a direct spectrophotometric method for unconjugated bilirubin, with caffeine reagent (Clin Chem 1986;32:1389-93). Because this method is independent of the protein matrix we used it for the preparation of bilirubin standards (Clin Chem 1987;33:1817-21). Now, in this paper, we utilize the caffeine reagent in ... WebMar 10, 2024 · The purpose of this study was to apply the principles of direct spectrophotometric assays for measuring fHb in an automated routine chemistry analyzer without reagents. And we evaluated analytical performance of new method and …

WebDec 1, 2004 · The Harboe intra-assay coefficient of variation was < or = 1.85% across all concentrations, which contrasted with 30% at and around 0.1 g/l for the TMB method. The Harboe spectrophotometric method ... WebMar 1, 1988 · We evaluated the analytical performance of a direct spectrophotometric scanning procedure for quantitation of plasma hemoglobin. Hemoglobin concentration was determined using formulas employing absorbance values at 415, 380, and 450 nm (Harboe, or “Allen correction” formula) or at 415, 380, and 470 nm (Noe, or “polychromatic” formula). WebA highly sensitive spectrophotometric method for determination of cobalt(II) in the presence of Triton X-100 has been described. 117 Simultaneous determination of Cr(VI) and Fe(III), backed up by chemometric approaches, has been reported, using mixed organic reagents in a nonionic micellar solution of Triton X-100. 118 skullcandy wireless earbuds purple
