HIGH-PERFORMANCE Rxi® COLUMNS

Rxi®-17Sil MS

Similar to: (50%-phenyl)-methylpolysiloxane

Rxi®-17Sil MS Columns

(fused silica)

(midpolarity Crossbond® phase)

• Excellent inertness and selectivity for active environmental compounds,

such as PAHs.

• Low bleed for use with sensitive detectors, such as MS.

• 340/360 °C upper temperature limits.

• Equivalent to USP phase G3.
