Great columns at a great price!
Application Area: Industrial hygiene analysis
"Restek columns are very consistent from year to year. I have been using their GC and HPLC columns for over 20 years and have never had a problem."
The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications.
The general-purpose Restek C18 is a conventional monomeric octadecylsilane column suitable for analyses of a wide range of compounds from acidic through slightly basic.
