固定相介紹:
1. β-DEX 110:非鍵合相,SPB-35(35%苯基/65%甲基聚硅氧烷)中含20%全甲基化β-環糊精。應用:揮發性手性異構體(酮、酯、烷烴、烯烴、醇、酸、醚等)。溫度范圍:30℃至230℃。
2. α-DEX 120:非鍵合相,SPB-35(35%苯基/65%甲基聚硅氧烷)中含20%全甲基化α-環糊精。對小分子手性異構體的分離有獨特的選擇性,也適用于分離同分異構體(如苯酚、二甲苯等)。溫度范圍:30℃至230℃。
3. β-DEX 120:非鍵合相,SPB-35(35%苯基/65%甲基聚硅氧烷)中含20%全甲基化β-環糊精。應用:揮發性手性異構體(酮、酯、烷烴、烯烴、醇、酸、醚等),與β-DEX 110有相同的手性選擇性但洗脫順序不同。溫度范圍:30℃至230℃。
4. γ-DEX 120:非鍵合相,SPB-35(35%苯基/65%甲基聚硅氧烷)中含20%全甲基化γ-環糊精。手性異構體的洗脫順序常常跟α-DEX和β-DEX柱相反,可作為α-DEX和β-DEX的補充。溫度范圍:30℃至230℃。
5. α-DEX-225:非鍵合相,SPB-20(20%苯基/80%甲基聚硅氧烷)中含25% 2,3-二-O-乙酰基-6-O-TBDMS-α-環糊精。可用于分離揮發性手性分子,包括醇、醛、羧酸、環氧化合物、酯和鹵化物。溫度范圍:30℃至230℃。
6. β-DEX 225:非鍵合相,SPB-20(20%苯基/80%甲基聚硅氧烷)中含25% 2,3-二-O-乙酰基-6-O-TBDMS-β-環糊精。對于小分子手性異構體分離有特異的選擇性,適用于醇、醛(如二苯基丙醛)、酯(如甲基馬來酸,甲基乳酸)、香料和酮等。溫度范圍:30℃至230℃。
7. γ-DEX 225:非鍵合相,SPB-20聚(20%苯基/80%甲基硅氧烷)中含25% 2,3-二-O-乙酰基-6-O-TBDMS-γ-環糊精。溫度范圍:30℃至230℃。
8. α-DEX 325:非鍵合相,SPB-20(20%苯基/80%甲基聚硅氧烷)中含25% 2,3-二-O-甲基-6-O-TBDMS-α-環糊精。溫度范圍:30℃至230℃。
9. β-DEX 325:非鍵合相;SPB-20聚(20%苯基/80%甲基硅氧烷)中含25% 2,3-二-O-甲基-6-O-TBDMS-β-環糊精。β-DEX 325與CHIRALDEX B-DM的化學性質和用途都相同,主要區別在于摻入聚硅氧烷載體中的二甲基衍生的環糊精濃度不同。溫度范圍:30℃至230℃。
10. γ-DEX 325:非鍵合相;SPB-20聚(20%苯基/80%甲基硅氧烷)中含25% 2,3-二-O-甲基-6-O-TBDMS-γ-環糊精。溫度范圍:30℃至230℃。
