Abstract: A liquid sample analyzer has an analysis chamber adapted to receive sample material to be analyzed, sensor means coupled to the analysis chamber for providing an output signal related to a constituent of the sample material, and sampler apparatus that includes structure defining a sample intake flow path that has an inlet port and is connected to the analysis chamber, and rinse apparatus in communication with a waste system. A wiper member slides along the intake tube for wiping sample residue from the outer surface of the intake tube. A drive moves the sample inlet port between a sample intake position in which the inlet port is exposed to the operator and a reset position in which the inlet port is aligned with and the wiper is seated on the rinse apparatus.
