Eluent and Regenerant Reservoirs
The ICS-90 top cover is molded to hold one eluent reservoir assembly
(P/N 057711) and one regenerant reservoir assembly (anion, P/N 057712;
cation, P/N 057713).
• Eluent carries the sample through the ICS-90 and facilitates the ion
separation process. Different types of eluents are used, depending on
the analyses performed. For example, an ICS-90 configured for anion
analyses uses carbonate eluent, and an ICS-90 configured for cation
analyses uses methanesulfonic acid (MSA) eluent.
• Regenerant “regenerates” the suppressor’s ability to suppress eluent
conductivity. An ICS-90 configured for anion analyses uses dilute
sulfuric acid regenerant. An ICS-90 configured for cation analyses
uses tetrabutylammonium hydroxide (TBAOH) regenerant.
