Unfortunately, we do not offer guards with a 3.5µm particle size. The closest option I would recommend is 1.50434.000. It is 5 μm particle size but it will have no impact on the results because of the very small column volume.

一般說明
SeQuant® ZIC®-HILIC亲水作用色谱柱专用于保留和分离所有类型的极性和亲水性化合物，实现高选择性和重现性的可靠色谱分析。 ZIC®-HILIC填料的硅胶基质键合着强极性永久两性离子。两性离子电荷1:1平衡，使ZIC®-HILIC色谱柱整体呈中性，具有微弱但重要的离子作用，更利于发挥分离选择性。进行ZIC®-HILIC色谱柱的方法开发时，不受pH影响的永久两性离子更方便选择性调整，保证在优化洗脱剂时，只有分析物受到影响（色谱柱不受影响）。色谱柱的100 Å孔径使其成为在亲水作用色谱条件下分离极性小分子的理想选择。250 mm x 2.1 mm内径的色谱柱规格驻留体积小，是使用UHPLC或优化的HPLC仪器分离复杂样品的最佳选择。优越的保留能力和稳健可靠的性能使得SeQuant® HILIC色谱柱受到全球众多实验室的欢迎。比如，美国FDA（美国食药监）已经推荐SeQuant® ZIC®-HILIC色谱柱用于三聚氰胺及相关物质的分析。SeQuant® HILIC色谱柱具有高稳定和低流失的优点，因而十分适合对背景要求较高的LC-MS应用，高背景会导致信号抑制，并干扰定量检测，同时还会更加损害仪器。高稳定性也令这种高效HILIC色谱柱同样适合传统的HPLC分析。详见Supelco HPLC色谱柱系列和方法开发资料：手册：HPLC和UHPLC色谱柱选择指南 手册：HPLC实用指南——方法开发指南
