low-polarity phase; Crossbond diphenyl dimethyl polysiloxane
The diphenyl dimethyl polysiloxane stationary phase is the most popular GC stationary phase and is used in a wide variety of applications. All residual catalysts and low molecular weight fragments are removed from the MXT-5 polymer, providing a tight monomodal distribution and extremely low bleed.
