A sample processing system for use with analysis apparatus includes tubular structure that defines a continuous elongated flow chamber. The tubular structure has an inlet port at one end, an outlet port at the other end, and a sample inlet port in communication with the continuous elongated flow chamber between the inlet and outlet ports. A first pump flows diluent at a first rate through the inlet port for flow through the continuous elongated flow chamber, and a second pump flows a liquid mixture from the continuous elongated flow chamber through the outlet port at a rate greater than the first rate. With the sample inlet port submerged in a sample to be analyzed, the sample is aspirated through the sample inlet port into the flowing diluent stream in the continuous elongated flow chamber for dilution and application of the diluted sample mixture to sample analysis apparatus for analysis.
