摘要： The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group. In some examples, the present disclosure can include a chromatographic system having a chromatographic column having a stationary phase with a chromatographic substrate containing silica, metal oxide, an inorganic-organic hybrid material, a group of block copolymers, or a combination thereof.

摘要： A mobile phase including a lithium salt flows through a stationary phase including an oxygenated metal compound with affinity to the lithium salt through a Lewis acid-Lewis base interaction so that the oxygenated metal compound captures the lithium salt through the Lewis acid-Lewis base interaction. An eluent flows through the stationary phase to release the lithium salt captured by the oxygenated metal compound into the eluent. The eluent includes a Lewis base or a Lewis acid that disrupts the Lewis acid-Lewis base interaction between the lithium salt and the oxygenated metal compound. The eluent including the released lithium salt is collected after the eluent flows through the stationary phase.

摘要： Chromatography method in which a gaseous, liquid or supercritical mobile phase containing species to be separated is circulated through a packing, said packing being characterized in that: —it comprises a plurality of capillary ducts extending in the packing between an upstream face through which the mobile phase enters the packing and a downstream face through which the mobile phase leaves the packing—the material of the walls comprises a first population of connected pores, providing passages from one duct to the next enabling molecular diffusion to take place between adjacent ducts, pores having a mean diameter (dpore) of greater than 2 times the molecular diameter of at least one species to be separated—the diameter of the ducts is less than 50 μm.

摘要： In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05≤(b/c)≤100, and a≥0.
