Abstract: An analyzer apparatus for analyzing components of a sample has a conduit and an electrochemical sensor in the conduit. The sample is passed through the conduit using a carrier liquid that is immiscible with the sample and non-wetting of the inner wall of the conduit to reduce instabilities in the apparatus due to undue fluid movement.
Abstract: A method for measuring or controlling the volume of a liquid segment confined within a tube and having a leading edge and a trailing edge. The tube is exposed to radiation at an angle and radiation refracted from the inner surface of the tube is measured at the leading and trailing edges of the segment while the liquid segment is moving through the tube.
