What is Micro-continuous Flow System for Wet Chemical Analysis about?
A new continuous ̄ow system based on controlled pumping of exact volumes of sample and reagents into a microbore manifold has been designed. The piston type pumps are made of Al 2 O 3 ceramics and driven by a stepper motor with 48 steps per rotation. One pump per liquid (sample, reagents) is used. For each complete rotation a repeatable and exact volume in the range 3±4 ml is delivered. Samples are introduced sequentially into the system without being separated by any rinsing or conditioning carrier solution. The mixing channels in the manifold are zigzagged in order to promote secondary ̄ow and thereby ef®cient mixing through inertial effects. Several types of dedicated manifold have been manufactured with volumes in the range 10±30 ml. Optical measurement is made vertically against the ̄ow direction using a light emitting diode as the light source. The detection volume is 0.25 ml. When a new sample is introduced into the system, a signal level typical for the analyte concentration in the sample is rapidly obtained. The detector signal oscillates because of the short and stepwise movement of the liquids in the system. The chemical reactions occurring while the liquids are stati
