Abstract
A method for the simultaneous concentration of multiple toxins from large volumes of water. The method includes the steps of providing a disposable separation centrifuge bowl, the centrifuge bowl including a positively charged material at it's inner core. A large water sample contaminated with toxins from a group consisting of protozoa, bacteria, bacterial spores, and toxins is delivered to the centrifuge bowl. A centrifugal force is applied to the separation bowl. The water sample is concentrated to remove large particles of the toxins in the bowl due to the centrifugal forces. The concentrated water sample is passes through the positively charged inner core to capture any remaining concentrated targets by electrostatic forces and the concentrated targets are eluted.
