Abstract

An analytical instrument measures carbon content of a liquid sample. The instrument includes a sample inlet, a reagent inlet, a rinsing solution inlet, a reaction chamber, a waste outlet and a syringe pump. A multiple port valve has a plurality of ports which are coupled to the sample inlet, the reagent inlet, the rinse solution inlet, the reaction chamber and the waste outlet. The valve also includes a primary port coupled to the syringe pump and selectively fluidically couplable to each of the remaining ports.
