Claim 2:
3. 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 and having a second vacuum configuration to fluidically couple a second vacuum line with the sample reservoir, wherein the valve system includes a valve fluidically coupled to an inlet of the sample reservoir and an outlet of the sample reservoir, and wherein the valve is selectively coupled to the first vacuum line and the second vacuum line via a fluid 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.
