Ascentis Express ES-Cyanol/液相色谱柱
Ascentis系列液相色谱柱是目前sigma-aldrich公司旗下分析品牌Supelco的主打色谱柱品牌。具有如下优点: —B型超高纯球形硅胶基质,具有良好的表面惰性、重现性和稳定性— 现代键合工艺优化了键合相的表面覆盖率、最大化稳定性,同时也减小了键合相的流失、降低了不必要的次级保留效应—多种化学键合相和硅胶柱提供了较宽的选择性—具有增强极性化合物保留的化学键合相,如Ascentis RP-Amide(反相酰胺)柱—极低的柱流失、基线平稳,适用于LC-MS—多种色谱柱型号满足从分析到制备的规模—高表面积硅胶拥有高的色谱柱载样量,非常有利于制备色谱 此外为满足广大用户应用的需求,Sigma-Aldrich公司推出《Ascentis液相色谱柱应用谱图集》。该应用谱图集聚焦药物、食品、农残和环境等行业,包含大量热门检测应用,提供了两百多个液相应用图谱,并提供中文名、英文名、CAS号索引。欢迎致电010-82796427或email至feimeisi@vip.163.com 索取该应用谱图集资料。suitable for L10 Per USPGeneral descriptionAscentis® Express 5 micron ES-Cyano HPLC column is a high-speed, high-performance liquid chromatography column based on 90? Fused-Core® particles. The Fused-Core particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0.6-micron thick porous shell and the overall particle size of 5-microns. The sterically protected, extensively endcapped diisopropyl-cyanopropylsilane stationary phase of Ascentis Express ES-Cyano provides a stable, reversed-phase packing that can be used for basic, acidic, or neutral compounds.PH 范围:2-9,温度范围:≤60℃,孔径:90A,ENDCAPPED: YES,Ascentis Express ES-Cyano 液相色谱柱 各种规格(粒径:5um)内径(mm)长度(CM)产品编号包装规格2.1250557-U1 EA2.1350558-U1 EA2.1550559-U1 EA2.17.550562-U1 EA2.11050563-U1 EA2.11550564-U1 EA2.12550566-U1 EA3.0350567-U1 EA3.0550568-U1 EA3.07.550569-U1 EA3.01050570-U1 EA3.01550574-U1 EA3.02550575-U1 EA4.6350577-U1 EA4.6550581-U1 EA4.67.550583-U1 EA4.61050585-U1 EA4.61550588-U1 EA4.62550591-U1 EA配套保护柱芯粒径(um)长度*内径(mm)产品序号包装规格55 * 2.150592-U3 EA55 * 3.050593-U3 EA55 * 4.650597-U3 EAAscentis Express 液相色谱柱 保护柱卡套53500-U 1 EA
