十大理由购买PerkinElmerElite系列毛细柱1. 顶级品质高强度熔融石英2. 每一个管柱都单独检验测试合格3. 结果重现性好4. 交联和结合固定相5. 坚固的柱框架6. 好的分离度7. 可用固定相选择宽广8. 基线低流失9. 基线噪音更低10. 柱长度为5-105M为什么选择熔融石英?管柱的质量受许多因素影响。熔融石英被认为是最纯净的玻璃,较少有氧化金属(刘易斯酸位)和氢键(表面硅羟基)组。固定相是交联(聚合),并连接到柱表面,确保高度的稳定性,从而降低了在高温下固定相的流失。柱的优越惰性意味着酸性和碱性化合物可以在同一柱上进行分析。选择正确的固定相比较以前要求的许多各种各样的填充柱,毛细柱的固有效率(大量理论塔板数)允许您选择的固定相类型较少。也许更重要的是——因为毛细柱柱效更高,所以您会看到较窄,较高的峰能得到更好的分离度,以及更容易用您的数据系统进行积分。小峰的识别因为基线流失和基线噪音的降低而更加方便。PerkinElmer的非极性Elite-1将优先保留非极性化合物,同时珀金埃尔默Elite-200柱的固定相能为含孤对电子(如硝基和羰基)分析物提供高选择性。Elite-WAX聚乙二醇柱对醇等极性化合物具有高度选择性。我需要什么样的长度?通常毛细柱的长度可在15至105米之间。柱的长度越长,分离度越高,但这同时也增加了分析时间。柱的长度增加一倍,只会使分离度增加约40%,但是在等温条件下,分析时间会延长了一倍。如果使用程序升温,则分析保留时间更取决于温度而不是柱的长度。珀金埃尔默 提供的柱长度通常为5、10、12、15、25、30、50、60、75、100和105米,同时也和柱i.d有关。更多信息,请参考: elite系列毛细柱.pdf
