1. A method of treating a sample within a microfluidic analysis system, comprising the steps of:

  • a) providing a main channel having “

    a trapping zone suitable for trapping packing material;

    b) providing a slurry of a reagent treated packing material prepared in a solution having a predetermined composition of a solvent;

    c) inducing a flow of said packing”

    material into said trapping zone through a flow channel connected to said trapping zone so as to load said trapping zone and form a packed bed of said packing material;

    d) flowing a sample containing analytes through said packed bed, said reagent treating the sample, whereby. The sample leaving the trapping zone has an altered analyte composition.
