一般描述
比 C18 疏水性更小的相。对于极性和非极性化合物，保留性都比 C18 更小。将含低于 5% 有机溶剂修正的流动相用于 C8 柱上，而不是 C18 柱上。极性化合物在 C8 柱上比在 C18 柱上的保留性相对更强。
应用
- Chromatographic behaviour of ionic liquid cations in view of quantitative structure-retention relationship.: This study explores the chromatographic behavior of ionic liquid cations using quantitative structure-retention relationships (QSRR). The SUPELCOSIL™ LC-8 HPLC Column was utilized to analyze retention data for various ionic liquids, providing insights into their separation mechanisms and potential applications in analytical chemistry (Molíková et al., 2010).
- Liquid chromatographic method for the determination of lidocaine and monoethylglycine xylidide in human serum containing various concentrations of bilirubin for the assessment of liver function.: The research presents a liquid chromatographic method using the SUPELCOSIL™ LC-8 HPLC Column to determine lidocaine and its metabolite in human serum. This method is particularly useful for assessing liver function by measuring drug metabolism (Piwowarska et al., 2004).
- LC determination of morphine and morphine glucuronides in human plasma by coulometric and UV detection.: The research describes a method for the determination of morphine and its glucuronides in human plasma. Utilizing the SUPELCOSIL™ LC-8 HPLC Column, the study demonstrates the method′s sensitivity and applicability in pharmaceutical analysis (Ary et al., 2001).

Explosives such as 2,4,6-trinitrotoluene (TNT), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) are widely distributed environmental contaminants. Complete chromatographic separation is necessary in order to accurately determine and quantify explosives and their degradation products in environmental samples and in (bio)transformation studies.
