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. When the sample inlet port is in the sample intake position sample material is flowed into the sample intake flow path and when the sample inlet port is in reset position cleaning fluid is flowed through the sample flow path and against a surface of the wiper member for removing sample residue from the wiper member.
