β -DEX225 手性气相毛细管色谱柱 24348
产品特点: β-DEX225 手性气相毛细管色谱柱:温度限值:* 30°C 至 230°CGeneral description:The Supelco β-DEX 225 is a modified form of the β-DEX 325 phase, and employs acetyl derivatives at the 2,3-positions instead of more traditional methyl derivatives. The chiral stationary phase in β-DEX 225 columns contains 2,3-di-O-acetyl-6-0-TBDMS-β-cyclodextrin embedded in an intermediate polarity phase. These columns provide unique selectivity for enantiomeric separations of small molecules: alcohols, aldehydes (e.g., 2-phenylpropionaldehyde), esters (e.g. methyl malate, methyl lactate), flavor compounds and ketones.material fused silicadescription GC capillary columnBeta value 250df 0.25 μmapplication(s) gas chromatography (GC): suitableL × I.D. 30 m × 0.25 mmmatrix active group non-bonded 25% 2,3-di-O-acetyl-6-O-TBDMS-β-cyclodextrin in SPB-20 poly(20% phenyl/80% dimethylsiloxane) phasecolumn type capillary chiralmode of chromatography Chiral 色谱柱的应用:DEX225 - 二乙酰基衍生化环糊精和二甲基衍生化环糊精,为目标手性化合物或位置异构体分离提供了更多的选择, 能分离挥发性手性分子,包括醇、醛、羧酸、过氧化物、酯和卤代化合物。 订货信息:β-DEX225 手性气相毛细管色谱柱内径(mm)长度(m)膜厚(μm)订货号0.25300.2524348
