  • System and a method for using a small suppressor column in performing liquid chromatography
    Patent number: 5567307
    Abstract: A method and a system for ion chromatography are disclosed. The system includes a small capacity suppressor column for suppressing the conductivity of the eluant carrying the ionic species being tested. The size of the suppressor column permits regeneration of the suppressor column between each sample tested to provide accurate and precise test results for every sample. The method permits regeneration of the suppressor column during the loading of each sequential sample to prevent impairment to productivity.
