Ascentis Express F5/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 L43 Per USPGeneral descriptionAscentis Express 5 μm F5 is a high-speed, high-performance liquid chromatography column based on the highly efficient Fused-Core particle design. The bonded, endcapped, dimethylpentafluorophenyl-propylsilane stationary phase of Ascentis Express 5 μm F5 provides a stable, reversed-phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines. In addition to forming π-π and mildly steric interactions, F5 phases also retain compounds by polar interactions. As a result of having both polar and non-polar character, F5 phases can show dual-mode retention behavior, sometimes producing a “U-shaped” retention as a function of acetonitrile content of the mobile phase, with retention increasing at both low and high concentrations of ACN (reversed-phase and HILIC retention modes). Ascentis Express 5 μm F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.PH 范围:1-9,温度范围:≤60℃,孔径:90A,ENDCAPPED: YES,Ascentis Express F5 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2.1250603-U1 EA2.1350604-U1 EA2.1550605-U1 EA2.17.550607-U1 EA2.11050612-U1 EA2.11550613-U1 EA2.12550614-U1 EA3.0350615-U1 EA3.0550616-U1 EA3.07.550619-U1 EA3.01050622-U1 EA3.01550623-U1 EA3.02550624-U1 EA4.6350625-U1 EA4.6550626-U1 EA4.67.550627-U1 EA4.61050628-U1 EA4.61550631-U1 EA4.62550632-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 * 2.150633-U3 EA55 * 3.050634-U3 EA55 * 4.650635-U3 EAAscentis Express 液相色谱柱 保护柱卡套53500-U 1 EA
