Spiro TMD

The Spiro TMD is a heated macro-porous PTFE Teflon® membrane desolvation module that reduces solvent derived polyatomic interferences in the ICPMS mass spectrum. Both aqueous and organic solutions can be desolvated, making the Spiro ideal for HPLC applications.

• Heated Macro-Porous PTFE Teflon® membrane.

• Desolvation of Aqueous & Organic Solutions.

• Reduces solvent derived oxide, hydride and carbide polyatomic interferences.

• Suitable for sample flow rates < 400µL/min through Apex.

• Removes volatile acid matrix, i.e. HCl, HF.

• Fast rinse out.

• Can be used with or without the Apex.

• Add membrane desolvation to standard introduction systems.

• Easy to maintain and clean. User replaceable membrane sheets.

• CeO+:Ce+ ratio approximately 0.03%.
