Abstract
A method detecting the presence or concentration of an analyte in a sample is described in which the sample is mixed with a particulate reagent to form a stable flowable suspension prior to introduction of the sample into an analytical device or detector in order to eliminate memory effects. Preconcentration of the sample bound to the particulate reagent improves sensitivity of the analytical method.
