COSMOSIL C18-MS-II

Nacalai Tesque COSMOSIL 15C18-MS-II Preparative HPLC Guard Column, 15µm, 120Å, 50mm I.D. x 50mm Length, 1/Pk

Product Number: 34527-41

COSMOSIL C18-MS-II is a monomeric type of C18 phase. A new endcapping treatment with polar groups for "shield effect" has extended the pH range and significantly improved peak shape for basic compounds. This phase is recommended for most of applications but particularly effective for low molecular weight organic compounds.

Features: 

• 3C18-EB - This phase with a better end-capping treatment offers improved peak shape and separation particularly for basic compounds.
• C18-MS-II - This phase is recommended for most applications but particularly effective for basic compounds.
• C18-AR-II - This phase is recommended for separations requiring acidic mobile phase conditions. It also shows superior molecular shape selectivity to monomeric type C₁₈columns.
• C18-PAQ - This phase is designed to offer superior retention of polar compounds and excellent reproducibility in highly aqueous mobile phases, even in 100% aqueous.

Available in the Following Configurations:

• 2.5C18-MS-Ⅱ - 2.5 µm Particle Size
• 3C18-MS-Ⅱ - 3 µm Particle Size
