Technical Support

For Xenoic® XAMS suppressors and ASUREX regenerators.

Frequently asked questions

Can I use XAMS with any HPLC and IC system?
Yes. The XAMS anion membrane suppressor with ASUREX regenerator fits to chromatography systems and detectors from Thermo, Metrohm, Shimadzu, Knauer, Cecil Instruments, Hitachi, Waters, Agilent, Dionex, Shodex and several other instrument manufacturers.

Is XAMS compatible with eluents containing both hydroxide and carbonate/bicarbonate?
Yes. The XAMS anion membrane suppressor with ASUREX regenerator is suitable for neutralizing aqueous eluents containing hydroxide, carbonate, bicarbonate and a combination of these.​

Can XAMS be used during gradients and to suppress strong eluents?
Yes. The XAMS suppressor with ASUREX regenerator can neutralize aqueous eluents with concentrations from 1 mM to 50 mM or more depending on the set-up and flow rate. For even stronger eluents we recommend the XAMS-HC high-capacity suppressor.

Is XAMS compatible with the SeQuant SAMS suppressor?
Yes, indeed. XAMS is fully compatible to the discontinued SeQuant SAMS suppressor previously produced by Merck Millipore.

Could XAMS replace my old Alltech suppressor now when its consumables are not available anymore?
Yes, certainly. XAMS can replace other type of suppressors and most often give similar or better performance.

Is XAMS compatible with organic solvents?
Not fully. Maximum allowed concentrations of organic solvents in the eluent is 8% acetonitrile or 5% methanol.

Why should I install a 100 psi pressure relief valve before the XAMS suppressor?
The pressure relief valve will protect the membrane in the XAMS suppressor from rupturing if exposed to high downstream pressures.

Are the ASUREX-AR1 cartridge and ASUREX-AS1 solution compatible with the SeQuant CARS system?
Yes absolutely. All consumables for the ASUREX regenerator are fully compatible with the SeQuant CARS system previously produced by Merck Millipore and distributed by Sigma-Aldrich, VWR and others.
