APPARATUS AND METHOD FOR SEPARATING PLASMA FROM BLOOD AND DELAYED WETTING

摘要

Devices and methods are disclosed herein for separating a supernate from a suspension. The apparatus consists of a sample zone, a controllable gate, and an analysis zone. The sample zone holds the suspension. The analysis zone passively transports a supernate formed from the suspension by capillary transport. A controllable gate prevents the suspension in the sample zone from flowing into the analysis zone. The controllable gate can be triggered after the supernate has separated from the suspension to allow the supernate to flow into the analysis zone.

1. A method for separating a supernate from a suspension and transporting the supernate, the method comprising:
holding the suspension in a sample zone; preventing the suspension in the sample zone from flowing into an analysis zone by a controllable gate; triggering the controllable gate after a supernate has separated from the suspension, thereby allowing the supernate to passively flow into the analysis zone; and promoting, by capillary transport, the flow of the supernate through the analysis zone.
