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.

A system for consistently performing liquid chromatography of ionic species, comprising: a transport assembly adapted to transport an eluant; a sample portion injector including a valve connected to the transport assembly to selectively permit introduction of a plurality of sequential sample portion

A system for consistently performing liquid chromatography of ionic species, comprising: a transport assembly adapted to transport an eluant; a sample portion injector including a valve connected to the transport assembly to selectively permit introduction of a plurality of sequential sample portions into the eluant, each sample portion containing at least one ionic species; an analytical column connected to the transport assembly and disposed to receive the plurality of sequential sample portion and eluant therethrough, wherein the at least one ionic species is separated from the sample portion; a suppressor column connected to the transport assembly downstream from the analytical column, wherein the suppressor column suppresses the electrical conductivity of the eluant; a regeneration assembly cooperating with the suppressor column to supply regenerant through the suppressor column, the regeneration assembly including a regenerant reservoir configured to receive a portion of regenerant; a deionized water delivery system to deliver deionized water to the suppressor column; and a valve assembly which controls the flow of the regenerant, the deionized water, the eluant, and the at least one ionic species through the suppressor column, wherein the valve assembly is automatically actuable to selectively provide fluid communication between the regenerant reservoir and the suppressor column to direct a flow of the portion of regenerant through the suppressor column between the introduction of each sample into the eluant, further wherein the valve assembly is actuable to direct the deionized water through the regenerant reservoir to force the portion of regenerant out of the regenerant reservoir and into the suppressor column.
