Abstract:
A method of generating a high purity eluant for detecting sample ions comprising:providing a water source; providing an eluant generating source comprising counter-ions of the sample ions and a fluid flow path for liquid flow through the eluant generating source, the fluid flow path in liquid communication with the water source, wherein the fluid flow path is the only path for liquid flow through the eluant generating source; flowing water to the eluant generating source and performing electrolysis of the water in the fluid flow path to generate electrolysis ions having the opposite charge of the sample counter-ions wherein the electrolysis ions are selected from the group consisting of hydronium ions and hydroxide ions; combining the electrolysis ions with the sample counter-ions to form a high purity eluant; flowing the sample ions and the high purity eluant through an analytical column to separate the sample ions; and flowing the separated sample ions to a detector where the sample ions are detected.
