Determination of Amisulbrom Residues in Agricultural Commodities Using HPLC-UVD/MS

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...

Determination of Ivermectin Residues in Bovine Liver Samples By ELISA and HPLC with Fluorescence Detection

ABSTRACT         Background and Objectives: Ivermectin is an anti-parasitic medication frequently used in many food-producing animals. This study aimed to investigate the level of ivermectin residue in liver samples collected from slaughterhouses in Qazvin Province, Iran.         Methods: Overall, 88 bovine liver sam...

[Determination of sulfite residues in foods by using the modified rankine apparatus and HPLC].

A method for measuring sulfite residues in foods by using the modified Rankine apparatus and HPLC was developed. Sulfites released from foods by bubbling of nitrogen gas and heating for 15 minutes with an electric burner weRe absorbed in 1% triethanolamine solution and detected as sulfite ion by HPLC with a UV detector at 240 nm, using an anion exchange column, IonPac AS9-SC, with 1.8 mmol/L so...
