一般說明
保留机制：反相
样品基质相容性：水溶液（生物流体、水）
样品基质相容性：水溶液（生物流体、水）
- 亲水改性苯乙烯聚合物
- 开发用于从水样中提取多种化合物
- 保留主要基于反相；然而，由于该相是亲水改性的，它也适用于极性化合物。
- 被保留和回收的更具极性的化合物的例子包括（但不限于）： 吡哆醇（logPo/w -0.56）、核黄素（logPo/w -2.02）、生物素（logPo/w 0.11）。
應用
Supel™-Select HLB SPE管可用作萃取柱柱体，用于固相萃取，运用液相色谱电喷雾电离串联质谱法测定水样品中的抗生素。
特點和優勢
- 价格低，样品制备性能出色
- 适合通用方法 - 在方法开发过程中节省时间、金钱和令人头痛的事
- 更大的容量允许更小的床重 = 更小的洗脱体积 = 节省样品处理时间
- 抗过度干燥，可使用更强的方法
- 低 UV 和 MS 可萃取物，可降低背景并提高灵敏度
- 严格的生产和 QC 指南提供更高的批次间、管间和井间一致性，以提高准确性和精密度

Select HLB SPE是一种亲水性聚合物相，用于从水性基质中提取分析物。在本文中，它将用于从血浆中提取他汀类药物，以及从饮用水中提取48种药物分析物。
Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.
