Restek – Inert HPLC Columns

Restek logo

Analyzing compounds that have nonspecific adsorption (NSA) or nonspecific binding (NSB) to metal surfaces in LC columns have historically been a challenge. Poor peak shape and sensitivity are key indicators that polar, usually acidic compounds are interacting with the metal surfaces in the column, causing poor data quality.

Restek Inert HPLC ColumnsRestek’s new inert column technology is designed to eliminate these active analytes in the column hardware, giving analysts greater confidence in their data when working with metal-sensitive analytes.
