Crossbond® 5% diphenyl/95% dimethyl polysiloxane
- General purpose columns for drugs, solvent impurities, pesticides, hydrocarbons, PCB congeners or (for example) Aroclor® mixes, essential oils, semivolatiles.
- Temperature range: -60°C to 350°C. (Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced maximum temperature.)
- Equivalent to USP G27, G36 phases.
The 5% diphenyl/95% dimethyl polysiloxane stationary phase is the most popular GC stationary phase and is used in a wide variety of applications. Rtx®-5/MXT®-5 columns are high quality 5% phenyl columns. All residual catalysts and low molecular weight fragments are removed from the polymer, providing a tight mono-modal distribution and extremely low bleed.
The MXT® columns offer rugged, flexible, inert, Silcosteel®-treated stainless steel.
