ION CHROMATOGRAPHY USING FREQUENT REGENERATION OF BATCH-TYPE SUPPRESSOR

摘要

An ion chromatography apparatus and method is provided using a frequently regenerated batch-type suppressor. Preferably, the suppressor is regenerated after every measurement. Regeneration can also occur prior to substantial (50 %) exhaustion or on a time-basis (10 % ... 50 % of measurement time). The suppressor requires only a small quantity of ion exchange material, about 5 % ... 100 % of separation column volume or 10 ... 20 times of separation column ion exchange capacity.
