Abstract:

Methods, compositions, devices and kits having a novel chromatographic material are provided herein for separating and identifying organic molecules and compounds, for example molecules and compounds containing electron rich functional groups such as carbon-carbon double bonds. The methods, compositions, and kits include a metal-thiolate chromatographic medium (MTCM) with a sulfur-containing functional group or a metal-selenolate chromatographic medium (MSCM) comprising a selenium-containing functional group covalently attached to a support medium, such that the sulfur-containing functional group or selenium-containing functional group is bound to at least one metal atom. The MTCM and/or MSCM has affinity and specificity to compounds having one or more carbon-carbon double bonds, and performs a highly efficient and rapid separation of samples yielding non-overlapping peaks of purified materials compared to traditional media.
