美国MicroSolv公司是全球领先的色谱耗材及试剂供应商为全球色谱提供从色谱柱、连接器、管路到试剂、样品瓶的所有色谱耗材和配件。这些高质量的耗材及配件能为您的实验提供稳定可靠的数据保证。广州绿百草生物科技有限公司是美国MicroSolv授权代理商RSA Glass 表面去活样品瓶让你的 GC、LC、GC-MS、LC-MS数据更可靠1.让你能检测到通常会被玻璃瓶吸附的低丰度分析物2.几小时以后再进样，样品的pH也不会发生变化3.防止样品在进样瓶中发生水解4.水作为样品溶剂时，没有凹液面5.非涂层技术使用专利技术的RSA Glass高品质 (Advanced Quality, AQ)样品瓶及内衬管能通过消除硅胶层从而有效去除样品管内壁的反应活性。常规制造的玻璃样品瓶由于表面含有金属及硅羟基而对实验结果产生不利影响。当使用常规硼硅酸盐玻璃自动进样瓶或内衬管时，样品溶剂（例如水）能使得样品瓶/样品管的表面硅羟基发生去质子化作用，而在样品瓶内壁形成负电荷。硅羟基的“ 酸” 属性能够导致碱性化合物在样品瓶内壁的吸附，同时也会改变样品溶液的pH值，使得一些容易发生水解的化合物在进样之前发生水解，而难以检测得到。普通玻璃进样瓶内的金属污染物会引起分析物的沉淀、螯合等化学变化。使用RSA Glass?样品瓶或内衬管会使得您的样品不会在样品瓶内发生丢失，不会发生pH变化等其他问题，使得您的色谱或色质联用分析更可靠，批间、日间的一致性更高，避免产生不可靠的数据。RSA?自动进样瓶及玻璃内衬管 并非使用表面涂层技术，不会产生涂层的脱离与破坏问题，是您进行LC, LCMS, GC 及GCMS分析的极佳选择。高效Cogent Diamond Hydride液相色谱柱对于从事代谢组学研究或者分析对象是高极性化合物的研究人员来说Cogent Diamond Hydride?亲水柱提供了一个非常有效的解决方案。Cogent Diamond Hydride?亲水柱非常适合分析氨基酸、有机酸、糖类及其他高极性化合物。例如三聚氰胺就可以使用Cogent Diamond Hydride亲水柱进行高效的分离Diamond-Hydride 亲水柱分析结果实例（UDP-葡萄糖、UDP-葡萄糖、UDP-半乳糖、磷酸半乳糖、葡萄糖、蔗糖、红细胞中的 UDP-葡萄糖、UDP-半乳糖、三磷酸腺苷（ATP）、ADP-葡萄糖、CDP-葡萄糖、糖核苷酸、胞嘧啶、胸腺嘧啶、尿嘧啶、鸟嘌呤、腺嘌呤、三磷酸腺苷（ATP）、一磷酸腺苷（AMP）、黄嘌呤-磷酸、鸟嘌呤-三磷酸、体液中的黄嘌呤、尿酸、次黄嘌呤、色胺、五羟色胺、多巴胺、L-天冬氨酸、L-精氨酸、L-精氨酸、L-赖氨酸、L-组氨酸、谷氨酸、赖氨酸、亮氨酸、异亮氨酸、L-甲硫氨酸、L-谷氨酸、甲基琥珀酸、戊二酸、草酸、肌酸、4-羟脯氨酸、天冬氨酸、鸟氨酸、叶酸、抗坏血酸、胆汁酸、柠檬酸、马来酸、反式乌头酸、马来酸、富马酸、3-羟基肉桂酸、矮壮素、甲哌啶、苯海拉明、4-二甲氨基吡啶、草甘膦（JP标准专用柱）、三聚氰胺、三聚氰酸、胍等）超长寿命的TYPE-C Silica HPLC硅胶柱，不含有自由硅羟基，可以在任何HPLC流动相下工作，即使是100%的纯水流动相。使用Si-H健代替硅胶表面原有的Si-OH健，更能抗酸水解，可以使用pH1.5的全水流动相。而且一根柱子可以做反相及反反相色谱-Aqueous Normal Phase (ANP)，与普通的HILIC模式色谱柱子相比最大的优点：同时对极性及非极性化合物有保留。几种有机酸的分离结果： 关于美国MicroSlove更多类型的色谱柱等产品可来电咨询：020-8393930075040-05P-2 Cogent HPS Amino HPLC Column 120A 5um 2.1mm x 50mm with Standard End Fittings.04650-ZF-150-X Neutral LPA Coated Capillary Zero Flow 50um ID by 150um OD. 3/pack.
