Abstract
Methods for determining total analyte concentrations and amounts, especially in combination with analyte separations are provided. Microfluidic devices are used to separate analyte mixtures and detect the individual analytes. Signal areas are summed for each individual analyte to quantitate the total analyte amount. Separate measurements of the total analyte sample are also used to determine total analyte concentration.
