07057-41 Cosmosil HILIC Packed Column 4.6* 250mm，5μm

Introduction:  

Nacalai tesque's Cosmosil chromatographic column has the advantages of affordable, high quality and long life.

Detailed introduction:  

The excellent characteristics of Cosmosil: 1. Ultra-high purity, fully porous spherical silica as the matrix: high column efficiency, low column pressure, long life 2. Nearly superior end-sealing technology, expands the PH application range (2-10) and; effectively reduces With tailing, it has better peak symmetry for basic compounds and chelates. 3. Because the single-point bonding technology is adopted, the batch-to-batch reproducibility of the chromatographic column is better, and the mobile phase equilibrium time is shorter. 4. High column efficiency and good selectivity. It has good adaptability and good reproducibility for complex samples such as traditional Chinese medicine. Cosmosil product classification list: Column name Stationary phase carbon content% Features and uses Cosmosil MS-II/PAQ (Cosmosil MS-II/PAQ suitable for analysis:) 5C18-MS-II Octadecyl 17% Widely used C18, suitable for separating basic compounds. 5C18-AR-II Octadecyl 16% Strong acid resistance, suitable for separating acid compounds and peptides. 5C18-PAQ Octadecyl 11% Suitable for separation of hydrophilic compounds, 100% water can be used as mobile phase. Cholester cholesteryl (cholesteryl group) 20% use conditions are the same as C18 column, the best choice for reversed-phase column. π-NAP Naphtylethyl group π-electron reversed phase column beyond phenyl column. 5PYE Pyrenylethyl group 18% binds to strong π-π interactions. The separation of structural isomers is very effective. 5NPE nitrophenylethyl group recognizes dipoles. 5PBB-R Pentabromobenzene (pentabromobenzyl group) dispersion effect. 5PE-MS phenylethyl group 10% interacts with C18π-π. 5CN-MS cyanopropyl group π- π interaction. Hydrophilic (highly polar) compounds that cannot be maintained on HILIC triazole group C18 columns can also be separated. Sugar-D secondary/tertiary amine is suitable for the analysis of monosaccharides and polysaccharides. The effect is excellent. Protein-R octadecyl group is suitable for the separation of proteins and peptides. C18-300 has higher separation and recovery. Buckyprep pyrenylpropyl group 17% fullerene preparation special column, toluene is the mobile phase. The preparation efficiency is 30 times that of C18. Buckyprep-M phenodiazin group 13% special column for metal fullerene. The separation and preparation of 5PBB pentabromo benzyl group includes high-carbon fullerenes mainly composed of C60 and C70.
