COSMOSIL 色谱柱 (CAS No.None)

Product Name:COSMOSIL HPLC Column

English Name:COSMOSIL HPLC Column

Aliases:COSMOSIL high-performance liquid chromatography column, Cosmosil series columns

Physical Properties:The COSMOSIL column series is based on ultra-pure silica gel and offers a wide range of bonded phases including C18, C8, C4, C22, phenyl, cyanopropyl, and amino groups. Particle size is 5 μm with pore sizes from 60 Å, 100 Å, to 300 Å. The C18-AR-II features polymeric bonding with nearly complete end-capping and excellent acid resistance; the C18-MS-II is monomerically bonded for separating a broad range of compounds. Columns with 1.0 mm, 2.0 mm, and 3.0 mm I.D. are available for effective solvent savings.

Uses:COSMOSIL columns are designed for high-performance liquid chromatography, covering reversed-phase, normal-phase, ion-exchange, gel filtration, hydrophobic interaction, and chiral separation modes. They are widely used in pharmaceutical, biochemical, environmental monitoring, and food analysis applications. The C18 series suits a broad range of compounds, PYE and NPE columns resolve structural isomers, Diol and HIC columns are ideal for protein and enzyme separation, Sugar-D is dedicated to carbohydrate analysis, and ion-exchange columns are used for biomolecule purification.

Technical Specifications:

Particle size: 5 μm, with larger sizes available for preparative columns.

Bonded phases: C18 (MS-II, AR-II, PAQ, P-MS), C8, C4, C22, TMS, PE, CN, NH2, PYE, NPE, PBB, Diol, HIC, and more.

Pore sizes: 60 Å, 100 Å, 300 Å; wide-pore AR-300 reversed-phase columns are recommended for proteins, peptides, and nucleic acids.

Column I.D.: 1.0 mm, 2.0 mm, 3.0 mm, 4.6 mm, and preparative sizes; the 2.0 mm semi-micro column consumes only 1/5 the solvent of a 4.6 mm column.

Acid resistance: C18-AR-II with polymeric bonding and nearly complete end-capping provides strong acid resistance, especially suitable for chelating compounds and acidic/alkaline analytes.
