Abstract: An apparatus for the determination of analytes in liquid samples is disclosed. The apparatus comprises in fluid connection a positive-displacement pump, a chamber in which the reagents specific for the analytes to be determined can be delivered, a detector, a second chamber and a device for the introduction of sample within the circuit and for the discharge. The apparatus also provides for apparatus to control flow and to control of the operation of each component. A process for the determination of the analytes is also disclosed.
