Simultaneous Determination of Tetracycline Antibiotics by 3-Phase Hollow Fiber-Liquid Phase Microextraction (HF-LPME) and HPLC-UV/Vis

Microextraction and Determination of Diclofenac in Biological Samples using Hollow Fiber Liquid Phase Microextraction Technique Coupled with HPLC-UV

In this study, hollow fiber liquid phase microextraction (HF-LPME) coupled with highperformanceliquid chromatography (HPLC) with UV detection was applied for preconcentrationand determination of Diclofenac sodium in biological fluids. Parameters affecting the extractionprocess including pH of donor phase and acceptor phase, type of extraction solvent, stirring rate,extraction time, and salt add...

simultaneous determination of acetaminophen and codeine in tablets by hollow fiber solid-phase microextraction combined with hplc-dad

Enrichment and determination of trace estradiol in environmental water samples by hollow-fiber liquid-phase microextraction prior to HPLC.

This paper presents a novel and simple cleanup procedure based on hollow fiber liquid-phase microextraction (HF-LPME) for the determination of trace estradiol in environmental. Estradiol was extracted from a 140-mL water sample (the donor phase) into the pores of the hollow fiber wall organic solvent, then into the organic solvent (the acceptor phase) in the lumen of the hollow fiber. Afterward...

Solid-Phase Extraction and Simultaneous Determination of Tetracycline Residues in Edible Cattle Tissues Using an HPLC-FL Method

In this assay, edible cattle tissues from local markets of Ardabil, a Province of Iran, were examined for residues of tetracycline antibiotics (tetracycline, oxytetracycline and chlortetracycline). In total, 110 samples of triceps, gluteal muscle, diaphragm, kidney and liver were randomly obtained from the local markets of the city of Ardabil. Solid-phase extraction (SPE) and high-performance l...

extraction and determination of fexofenadine and levocetirizine in human plasma by hollow fiber liquid phase microextraction and high performance liquid chromatography

a simple, inexpensive and efficient method was used for extraction and determination of fexofenadine and levocetirizine with three–phase hollow fiber liquid-phase microextraction and high-performance liquid chromatography. several parameters influencing the extraction recoveries such as the nature of organic extraction solvent, ph of donor and acceptor phases, stirring rate, extraction time and...
