HPLC Separation of Mixture of DMF and DMSO

April 25, 2019

HPLC Method for DMF (Dimethylformamide), DMSO (Dimethyl sulfoxide) on SHARC 1 by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of DMF (Dimethylformamide), DMSO (Dimethyl sulfoxide).

Dimethylformamide, DMF, is primarily used as an organic solvent and is miscible with water and most other organic liquids. Dimethyl sulfoxide (DMSO) is also a solvent. It can dissolve both polar and nonpolar compounds and is miscible with water and other organic liquids. Both compounds can be retained and separated using anhydrous (water-free) conditions using HPLC by SHARC 1 column, which uses hydrogen-bonding as a separation mechanism. The method uses a gradient of acetonitrile (ACN) and methanol (MeOH) mobile phase without the need for a buffer. UV detection used at 220nm.

HPLC Separation of DMSO and Glycine by Mixed-Mode Chromatography

July 16, 2009

Dimethyl sulfoxide is important polar aprotic solvent, which is frequently used in pharmaceutical drug manufacturing, desolution, etc. DMSO is used as one of the solvents on protein chemistry due to universal ability to dissolve small molecules like amino acids. Amino acids and DMSO are very polar and have no retention on reversed-phase columns. In this HPLC application DMSO and glycine are separated on Primesep 100 mixed-mode column. DMSO is retained by weak reversed-phase mechanism and very low organic concentration is required in order to achieve any retention. Glycine, like any other underivatized amino acid, is retained by weak reversed-phase and moderate cation-exchange mechanism. Method uses acetonitrile/water/TFA gradient and UV detection.

Condition

Column Primesep 100, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer TFA
Flow Rate 1.0 ml/min
Detection UV, 210 nm
