IRIS Polymeric SPE Columns

IRIS™ Polymeric SPE

Polymeric based SPE product line available in many configurations with 25-35 micron particle sizes and various surface chemistry for ion-exchange, hydrophilic and hydrophobic interaction.

Advantages of Polymeric SPE

• Excellent recovery - highly retentive nature of polymeric phases
• Absence of residual silanol groups
• High surface area that results in higher analyte capacity compared to silica based SPE
• Absence of leachables
• Inert to a wide array of solvents and pH range
• Reduced resin volumes for improved detection limits
• Resistant to dewetting
