RP-HPLC ‘• EVALUATION FOR SOME INSULIN INTERACTIONS [PDF]

Journal of Food and Dairy Sciences, 2006
In present study the RP-HPLC characteristics were used for the evaluation of insulin interactions. These characters such as retention time (RT), area under the peak (AP), peak height (PH), and peak width (PW) were all examined.

Speciation of Chromium Metal Ions by RP-HPLC [PDF]

Journal of Chromatographic Science, 2009
A high-performance liquid chromatographic method with UV detection, based on chelation with morpholine-4-carbodithioate (MDTC), has been developed for the speciation of chromium. Simultaneous preconcentration of Cr(III) and Cr(VI) in aqueous solutions was achieved by extraction of metal species in chloroform as MDTC complexes.

Determination of doxazosin mesylate in tablets by RP-HPLC

Indian Journal of Pharmaceutical Sciences, 2011
A simple, precise and rapid RP-HPLC method was developed for the determination of doxazosin mesylate in pharmaceutical formulations. The method was carried out on a Chromolith RP-C(18) column using a mixture of potassium phosphate buffer and methanol (40:60 v/v) and detection was done at 251 nm. The linearity range was 1-5 μg/ml.
