InertCap 35 is a medium polar column incorporating 35 % diphenyl and 65 % dimethylpolysiloxane. With stronger polarity than InertCap 25, InertCap 35 is optimal for the analyses of semivolatile compounds or solvent. Improved the stationary liquid phase and the maximum operating temperature is 360 ℃ . Designed for GC/MS, InertCap 35MS realized the world highest inertness and ultra low bleed.
