ABSTRACT
A concentrator device and method of concentrating a liquid sample were invented (Wick 2012a). A concentrator device may include a pressure vessel and a filter element disposed within the pressure vessel. The pressure vessel may include an inlet configured to introduce pressurized air into a first portion of the pressure vessel and a first outlet fluidly coupled with a second portion of the pressure vessel. The first outlet may be adapted to be opened and closed selectively. A second outlet may be configured to receive a capillary tube inserted into the first portion of the pressure vessel.
