Are Cogent TYPE-C Silica™ columns made with hybrid particles?

Reference Number: AA-00256 Created: 04/01/2012 07:35 PM Last Updated: 07/23/2016 12:06 PM

No, it is an evolution of standard, high purity, based deactivated, type-B silica with a very stable and unique surface that does not retain water as all other HPLC columns do. If you are using a commercially available silica based HPLC column, TYPE-C™ columns may be considered the same as what you are currently using for USP and other ISO methods.
