Claim 7:
8. A system comprising:
a valve system in fluid communication with a sample reservoir and a vacuum source, the valve system having at least a first vacuum configuration to fluidically couple a first vacuum line with the sample reservoir, a second vacuum configuration to fluidically couple a second vacuum line with the sample reservoir, and a third vacuum configuration that blocks fluid communication between the sample reservoir and the first vacuum line and that blocks fluid communication between the sample reservoir and the second vacuum line;
a sensor system configured to detect presence or absence of a fluid handled by the valve system; and
a controller communicatively coupled with the sensor system and configured to control operation of the valve system to block access of the first vacuum line to the valve system upon detection of the fluid at the valve system to isolate the fluid within the sample reservoir.
