Chromatographic Properties
The Restek® PFP Propyl is a great choice for the retention and selectivity of charged bases,
electronegative compounds, and amine-containing compounds. Unlike a conventional cyano
column, the Restek® PFP Propyl is much more amenable to LC-MS because it is more reliable
and efficient with acidic mobile phases. This versatile column is also compatible with highly
aqueous mobile phases and HILIC separations.

Chromatographic Properties
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.
