Any analysis that can be performed using the AutoSuppression Recycle Mode can be done
using the AutoSuppression External Water Mode. A constant source of deionized water having
a specific resistance of 18.2 megohm or greater is supplied to the regenerant chambers to
generate hydronium or hydroxide ions for neutralization.
!
AutoSuppression External Water Mode is used when organic solvents or metallic
contaminants are present in the eluent or sample, or borate is used as the eluent.
NOTE
! Because of its simplicity and equivalent performance, Thermo Fisher Scientific
recommends the use of Recycled Eluent Mode unless organic solvents or metallic
contaminants are present in the eluent or sample, or borate is used as the eluent.
