Abstract
The sample injection cell comprises a body and a bore through the body for receiving a probe to pass fluid sample into the bore. A transverse passageway into the body permits a diluent to enter the bore and be mixed with a sample in a predetermined ratio and be dispensed directly into the flow cell. The diluent simultaneously washes the probe when the probe is located in the bore. A waste basin forms part of an integral unit and is adjacent the bore so that fluid from a flow cell can enter the waste basin and then exit under gravity to a waste drain.
