Abstract
A fluid arrangement for analyzing a fluid sample using an electrochemical measuring apparatus having an analyzing device with an inlet port and an outlet port, the outlet port connecting to an outlet tube, the inlet port connecting to an inlet tube having a sample fluid receiving end, and the inlet tube connecting at a junction along its length to one end of a fluid supply tube, which fluid supply tube is connected at its opposite end to at least one fluid source containing a fluid. In a first mode, the fluid from the supply source flows through the fluid supply tube to the junction and the fluid then flows simultaneously in a proximal direction and a distal direction within the inlet tube from the junction, and in a second mode, a fluid sample is drawn through the inlet tube past the junction and into the analyzing module.
