ACM

A Peltier cooled Nafion® micro-porous membrane for removing residual solvent vapor in the sample aerosol stream from an Apex sample inlet system. Cooling the membrane improves desolvation efficiency and long term stability.

• Nafion membrane removes water and small polar organic compounds
• Reduces solvent derived oxide and hydride polyatomic interferences
• Chemical resistance similar to Teflon®
• Temperature stabilized at +3 °C, enhances long term stability
• Can be used to analyze volatile analytes such B, Hg etc
• Suitable for sample flow rates < 400µL/min through Apex
• Resistant to clogging, run samples with high TDS
• Sweep gas does not permeate through membrane, use N₂ or Ar as sweep gas
• Fast rinse out
• Simple to operate, compared to macro-porous membrane
• Resistant to clogging by organic compounds and salts
• Easy to maintain and clean. Membrane is located with-in a cartridge
• CeO+:Ce+ ratio approximately 0.05%
