Abstract
Methods for use with chemical analyzers aspirate a sample portion from one location to dispense it at a second location, aspirate another sample portion at that second location and dispense it at the first location, and measure the pressure values experienced inside a probe performing the aspirations and dispenses. By comparing the pressure values (or other values indicative of the viscosity or other relevant properties of the sample), the chemical analyzer can determine if the sample is sufficiently mixed or if the sample components remain separated and the method should be repeated.
