InertCap 225

InertCap 225 is a medium polar column bonded with 50% cyanopropylmethyl and 50% phenylmethylpolysiloxane. The cyano group in the stationary phase includes a triple bond and retains compounds stronger according to the increase of the number of unsaturated bonds by their dipole/dipole interactions. For this reason, InertCap 225 shows high separation efficiency for analyses of geometrical isomers.
