Claim 1:
2. The method of claim 1, wherein the first analyte concentrator assembly and the second analyte concentrator assembly are each fluid coupled with a fluid valve such that:
in a first valve configuration:
first, the discharged first effluent is fluid transferred from the first analyte concentrator assembly, through the fluid valve, and to the eluent generation module to be processed within the eluent generation module so as to produce the first eluent from the transferred first effluent;
second, the first eluent is transferred from the eluent generation module, through the fluid valve, and to the second analyte concentrator assembly to elute the second portion of the analyte retained by the second analyte concentrator assembly; and
third, the second concentrated analyte sample is fluid transferred from the second analyte concentrator assembly, through the fluid valve, and to the analyte detection module and analyzed therein, and

in a second valve configuration:
first, the discharged second effluent is fluid transferred from the second analyte concentrator assembly, through the fluid valve, and to the eluent generation module to be processed within the eluent generation module so as to produce the second eluent from the transferred second effluent;
second, the second eluent is transferred from the eluent generation module, through the fluid valve, and to the first analyte concentrator assembly to elute the first portion of the analyte retained by the first analyte concentrator assembly; and
third, the first concentrated analyte sample is fluid transferred from the first analyte concentrator assembly, through the fluid valve, and to the analyte detection module and analyzed therein.
