Abstract:
A reactor for intermittently inhibiting activity of a sample by controlling pressure applied to the sample, comprising:a fluid reservoir for containing a test reagent,a reactor body defining a chamber for receiving a sample, anda system for providing flow of the test reagent into said chamber while said chamber is pressurized, said system comprising:a first valve located in a first conduit in communication with said fluid reservoir,a second valve located in a second conduit in communication with said chamber,a first pressurizer located between said fluid reservoir and said chamber and in communication with said first conduit and said second conduit, anda third valve associated with said first pressurizer for venting said first pressurizer,with said first valve in an open position and said second valve in a closed position, said reservoir being in communication with said first pressurizer to allow fluid flow to said first pressurizer; with said first valve in a closed position, said second valve in an open position, and said third valve in a closed position, said pressurizer being in communication with said chamber to pressurize said chamber; with said first valve in a closed position, said second valve in an open position, and said third valve cycled between an open position and a closed position, said pressure in said chamber being pulsed between an activity-inhibiting pressure P.sub.1 and an activity-allowing pressure P.sub.2.
