Siltek-treated, stainless-steel MXT wall coated open tubular (WCOT) capillary columns are the best choice for high-temperature chromatography and other situations where the potential for column breakage is too high to rely on fused silica columns. For field instruments, process GCs, GCs with small ovens, etc., Restek MXT columns provide the strength of metal with the inertness of glass and are guaranteed to perform.
The diphenyl dimethyl polysiloxane stationary phase 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.
Features & Benefits
