COSMOSIL C18-MS-II
Reversed Phase / Monomeric C18
COSMOSIL 5C18-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.

Application for nitrosamine analysis
Application for nitrosamine analysis
Nitrosamines are a group of compounds that result from various pharmaceutical synthesis processes, especially amine reactions. They are potential carcinogens and genotoxins, and their unexpected presence in drugs has been the cause of some recalls and resulting drug shortages.
We have developed a chromatographic method which separates 8 nitrosamines on our 5C18-MS-2 column. This enables detection and quantification of these compounds of concern.
