ABSTRACT:
An automated matrix removal module is configurable to automatically withdraw a portion of sample containing an interferent. The module is further configurable to mix the portion of sample with a precipitating reagent selected to react with the interferent to form a precipitant and then filter mixture of sample and precipitant reagent through a filter. Finally, the module is further configurable to flush the precipitant from the filter.
