Two modes of liquid-liquid extraction in flow-injection systems were compared and applied to the fluorimetric determination of thiamine (Vitamin B(1)). The first included phase segmentation, but fluorescence was measured without phase separation. In this mode, thiamine was detected at concentrations

A new reversed-phase ion-pair high-performance liquid chromatographic (HPLC) method has been developed for the determination of the following bisphosphonic acids: alendronic acid (ALEN), etidronic acid (ETID), ibandronic acid (IBAN) and risedronic acid (RISE). Separation was achieved on a C(18) column

A sensitive method for the measurement of thiamine pyrophosphate in whole blood and erythrocytes, using a straight-phase high performance liquid chromatography (HPLC), is described. The method was based on sample extraction with trichloracetic acid, conversion of the vitamer to the

The photolysis of thiochrome (THC), an oxidation product of thiamine (vitamin B1) (THE), used for its fluorimetric assay, has been studied in the pH range 7.0-12.0. THC undergoes photooxidation to oxodihydrothiochrome (ODTHC) which is oxidized to a non-fluorescent compound (OP1)
