 Trace | Multi Trace is an online analysis system in a compact 
metal housing. Communication with the user is driven by an external com-
puter. As shown in the following figures, the front and side panels are 
equipped with the elements of the pre-assembled tubing set for analysis.
The actuator and sensor components are located on the outside of the 
housing. A standard or sample solution is fed into the analysis system by a 
pump(1b). One of the pinch valves (3) allows a selection of the solutions to 
be pumped. The buffer stream is driven by the upper pump(1a). A particle 
filter (2) removes smaller particles and air bubbles from the buffer stream.
