Abstract: A switching solenoid valve for use in a fluid handling apparatus comprising two input ports for inputting fluid samples, and a third port for outputting fluid from one of the first and second ports. The valve switches one of the two input ports to the third port. The valve is such that the path between the ports which is normally closed when the solenoid is unactuated, has at least one of a significantly lower dead space, significantly less flow perturbations, and significantly lower total included volume between ports, than the path which is normally closed. Such a valve provides operational advantages especially for use in capnographic systems for analyzing exhaled breath.
