This invention provides methods and systems for injection of analytes into a separation channel for resolution and detection. Samples can be preconditioned and concentrated by isotachophoresis (ITP) before the injection is triggered by a detected voltage event. Separation of analytes from other sample constituents can be enhanced using skewing channel ITP.

Analyte injection system

A method of modifying the concentration of reactants and carrying out a chemical reaction on a microfluidic device in which first and second reactants are delivered into a reaction channel combined, the second reactant different from the first reactant and capable of reacting with the first reactant. The first reactant is subjected to a stacking process, thereby producing a first stacked reactant. The second reactant is subjected to the stacking process, thereby producing a second stacked reactant. The first stacked reactant is exposed to the second stacked reactant so that the first stacked reactant and the second stacked reactant undergo a chemical reaction.

Method for modifying the concentration of reactants in a microfluidic device

A method of carrying out a chemical reaction on a microfluidic device in which a first reactant at a first concentration is delivered into a reaction channel; within the reaction channel the concentration of the first reactant is changed from the first concentration to a second concentration; and while at the second concentration the first reactant is exposed to a second reactant.
