Desalting Samples with RediSep Rf Gold® C18Aq Columns

11 Nov 2014

Compounds are often purified with solvents that contain salts or buffers that need to be removed prior to subsequent studies with the compound. The RediSep Rf Gold® C18Aq columns have the ability to adsorb compounds under highly aqueous conditions and are ideal for removing the salt from a sample. The method described also removes a large portion of water from samples dissolved in aqueous solvents facilitating evaporation. The procedure is similar to solid phase extraction, but on a larger prep scale.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
