Abstract

Apparatus for FIA (Flow Injection Analysis) consists of an operating panel on which there may be mounted a sample injection valve, a measuring cell, measuring instruments and flow connections such as couplings, T- branches. The sample injection valve consists of two bodies (11, 12) in sealing contact with each other and movable in relation to each other so that in two different positions of the valve bodies ducts (13a-f) in one body (11) are connected in various manners to ducts (14a-e) in the other body (12) and an intermediate position (C) all communication through the valve is closed off. The solutions are fed by the application of a constant gas pressure from a reservoir or reservoirs. The valve operates to advance a carrier flow, inject a predetermined amount of sample solution into the carrier flow, and add an additional one or more reagents and/or washing solutions. Connecting lines have the same diameter as the ducts and each is attached with an elastic sealing ring 19 which surrounds the line. The measuring cell may be for potentiometric photometric or spectrophotometric measurement. <IMAGE>
