Classification: CPC A  G | IPC A  G

Claim 10:
11. A system for drawing a solution, the system comprising:
a filter having an input port, a first output port, a second output port, and a flow path defined in part by the input port and the second output port;
a vacuum source in fluid communication with the first output port and operative to apply a vacuum to the flow path;
an actuator operative to facilitate movement of the solution along the flow path;
a flow exchanger having a first port, a second port and a third port, the first port in fluid communication with the second output port of the filter;
a dispenser in fluid communication with the second port of the flow exchanger;
a sensor for collecting a sample of the solution, wherein the sensor is in fluid communication with the third port of the flow exchanger;
a normally open one-way check valve disposed between the second output port of the filter and the first port of the flow exchanger and operative to restrict flow of the solution from the flow exchanger to the second output port;
a normally closed one-way check valve disposed between the sensor and the third port of the flow exchanger and operative to restrict flow of the solution from the sensor to the flow exchanger;
wherein the flow exchanger is operative to allow the solution to flow from the second output port to the dispenser via the first port and the second port of the flow exchanger without passing through the third port of the flow exchanger;
wherein the actuator facilitates movement of the solution from the dispenser to the sensor;
wherein the dispenser is directly coupled to the second port of the flow exchanger; and
wherein the normally open one-way check valve is directly coupled to the second output port and the first port.
