Fluidic chamber assembly. The inlet line (7) carries the buffer to the fluidic chamber. A sample line (5) connected to the sample reservoir (not shown) carries the sample fluid to the injection valve (6) where it is injected into the flow of the inlet buffer. The injection valve is held in place using a manifold mount (4). The fluid can then flow out through the priming line (8) or into the measurement chamber (2) depending on the orientation of the solenoid valve (not shown). A thermocouple (9) monitors the temperature inside the measurement chamber and the piezoelectric actuator connected at (3) can be used for dynamic mode operation. The outlet line (1) leads to a waste container.
