Rxi®-624SilMSColumns
(fusedsilica)
(midpolarityCrossbond® silarylenephase; equivalent to6% cyanopropylphenyl/
94%dimethyl arylenepolysiloxane)
• Lowbleed, high thermal stability column—maximum temperatures up to320 °C.
• Inert—excellent peak shape for awide range of compounds, including acidic and
basic compounds.
• Selective—highly selective for residual solvents, great choice forUSP<467>.
• Manufactured for column-to-column reproducibility—well-suited for validated
methods.
