摘要： An extraction column (1) is used, which includes a first column (10) having an adsorbent layer (100) with a silver nitrate silica gel layer (110) and a sulfuric silica gel layer (130) and a second column (20) detachably coupled to the first column (10) and filled with a trapping layer (200) capable of trapping an organic halogen compound. The trapping layer (200) includes a trapping material having a granular carrier containing aluminum oxide and fine particle-shaped silver held on a surface of the carrier. An aliphatic hydrocarbon solvent is supplied to the adsorbent layer (100) to which an organic halogen compound-containing solution has been added, and passes through the adsorbent layer (100) and the trapping layer (200) in this order. A solvent for extraction of the organic halogen compound is supplied to the trapping layer (200) from the lower side of the second column (20), and the extraction solvent having passed through the trapping layer (200) is obtained through a branched path (22).

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 capillary column includes a fused silica tubing, a polyimide coating over the fusing silica tubing, and a first plurality of integrated ferrules positioned along at least a first portion of the fused silica tubing and spaced apart from one another by a first fixed interval. Each of the first plurality of integrated ferrules includes a first deformable surface and a second deformable surface. The first plurality of integrated ferrules are secured to the column through deformation of the first deformable surface and the second deformable surface is configured to form a seal with a junction when secured with a nut.

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.
