“…Thiamine (vitamin BI ) has been assayed by oxidation with alkaline potassium ferricyanide in various pharmaceutical preparations, with little interference from excipients and co-existing drugs other than ascorbic acid. The results compared well with those from an official method (88).…”

This paper reviews publications that combine the technique of flow injection (FI) with chemiluminescence (CL) and bioluminescence (BL) detection, from the earliest papers in 1979/80 to mid-1992, and refers exclusively to reactions occurring in solution. Air-segmented systems and liquid chromatography with CL detection are not considered unless FI has been used to pre-optimize the system. The applications have been categorized in terms of the type of CL reaction; there are separate entries for luminol, peroxyoxalate, other CL reactions and BL reactions. Each of the four sections includes a table of applications that lists the analyte, the nature of the reaction, the sample matrix and the limit of detection.

“…Calatayud and his co-workers gave an idea to discover new CL reactions, but their research work [28] had some drawbacks. For example, some compounds (such as vitamin K3 [31], pyruvic acid [32], vitamin B1 [33]), which are reported in Table 1 Symbols and definitions of topological indices in this work…”

“…This procedure is the official U.S.P. method and has been automated by flow injection (FI) with fluorimetric and chemiluminescence detection [3,4]. Other FI methods accomplish the oxidation of thiamine to fluorescent TC using Hg(II) [5], Cu(II) [6], strong anionic resins loaded with hexacyanoferrate(II) [7] and electrochemical oxidation [8].…”

A simple spectrophotometric method has been described for the determination of thiamine. The method is based on the precipitation of sulphur as barium sulphate using barium chloride after oxidation of thiamine by sodium hydroxide and hydrogen peroxide. Beer's law was obeyed over the concentration range from 2-32 µg/mL thiamine. The average of standard deviation was 1.18×10 -2 ; standard error, 5.20×10 -3 ; relative standard deviation, 0.51%; relative standard error, 5.40×10 -3 ; 95% coefficient, 1.48×10 -2 ; the limit of detection, 0.41 µg/mL; the limit of quantification, 1.38 µg/mL and recovery, 100.03% thiamine. Finally, the developed method was applied to the determination of thiamine in pharmaceutical formulations.Thiamine Oxidation Precipitation Determination Barium sulphate Spectrophotometric
