Js. Cosano et al., FLOW-INJECTION ANALYSIS OF WATER .2. INTEGRATED SYSTEM FOR AUTOMATIC MULTIDETERMINATION, Journal of automatic chemistry, 15(4), 1993, pp. 147-150
This paper describes an integrated flow injection (FI) system for the
determination of ammonia, sulphate and Fe(II)/Fe(III), which can work
unattended for long periods. The system was designed for the determina
tion of individual analytes in long series of samples. Each batch of s
amples requires manual selection of parameters and units, such as wave
length for monitoring, preconcentration column, loops and switching of
three valves to select the carrier, reagents and eluent. The system t
hen works automatically.
