Analysis of Tetracycline Antibiotics Using HPLC with Pulsed Amperometric Detection

Analysis of tetracycline antibiotics using HPLC with pulsed amperometric detection.

The analysis of tetracycline, oxytetracyline, chlortetracycline and doxycycline by high-performance liquid chromatography with pulsed amperometric detection using an anodized boron-doped diamond thin film (BDD) electrode is originally reported. The analyses were carried out using the mobile phase, phosphate buffer (0.01 M, pH 2.5)-acetonitrile (80:20; v/v), on a C18 column (250 x 4.6 mm i.d., 5...

Routine Citrus Juice Analyses Using Hplc with Amperometric Detection

Analytical methods useful for routine applications are ideally low-cost, simple to perform, and yield rapid results which are easy to interpret. Chroma tog raphic methods, par ticularly of complex samples such as fruit juice, are often difficult, can be expensive and time-consuming, and may yield results devoid of interpretation. With the proper choice of detector, the chromatographic analysis ...

DETERMINATION OF AMOXYCYLLIN AND CLAVULANIC ACID IN PHARMACEUTICAL DOSAGE FORMS BY HPLC WITH AMPEROMETRIC DETECTION

A simple and sensitive high performance liquid chromatographic method with electrochemical detection is described for the quantitative determination of the amoxycillin and clavulanic acid in pharmaceutical dosage forms. Separation of sample components occurs on a reversed phase C18 column with a mobile phase consisting of methanol-water-phosphate buffer. For the amperometric detection, the pote...
