High Performance Liquid Chroma tographic Analysis of Dicofol Acaricide

Flow Markers in Microreactors: A Generally Applicable Chroma- tographic Method for Monitoring Flow Rates During Reactions

Microreactors have found widespread use for continuous flow synthesis and reaction optimization. Flow rates are critical factors with respect to the latter application because they are used to set screening parameters such as reaction time and stoichiometric ratios. However, the set flow values of pumps for nanoliter to microliter volume reactors are quite often not sufficiently accurate. In th...

HIGH-PERFORMANCE LIQUID CHROMATOGRAPHIC ANALYSIS OF SULFUR MUSTARD REACTION WITH AMINO ACIDS AND PROTEINS

The interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. Rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. At different time intervals, plasma and urine samples were collected. The binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-i...

Simulataneous Analysis of Trimethoprim and Sulphamethoxazole Drug Combinations in Dosage Forms by High Performance Liquid Chromatography

A sensitive high performance liquid chromathography (HPLC) analytical procedure was developed for the quantitive determination of trimethoprim (TM* and sulphamethoxazole (SM) in commercial dosage forms. C18 analytical column (stainless steel, 25 cm * 4.6 mm i.d.) was packed with 5-*m particles of the reversed phase material and used for assays. Mobile phase containing 0.025 M sodium phosphate...

High-Performance Liquid Chromatography Determination of Methotrexate in Plasma

This article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (MTX) in plasma. Samples were collocted from children receiving high-dose MTX at shafa Hospital (Ahvaz University of Medical sciences, Ahvaz, iran) at various times after the end of eachinfusion. Plasma was deproteinized with trichloroacetic acid and the supernatant was i...
