✦ Synopsis

Multicomponent batch-injection analysii is demonstrated for the first time using a multi-channel pipette and an array of three ion-selective electrodes. With this approach, simultaneous determhtation of species for which suitably selective sensors are available can be quickly and easily achieved. The number of sensors in the array can be easily expanded to match the number of channels in the multi-pipette (eight at present). Signals from the array are monitored with a multi-channel I/O card (Analog Devices RTI-815) fitted inside a 4&DX PC compatible computer. Data display and processing is achieved using routines written in Microsoft QuickBasic (version 4.5).

An ammonium detection system using ion-selective electrodes (ISEs) in flow-injection analysis (FIA) is described. Because of the low selectivity of the nonactin ammonium selective electrode toward some common ions, notably potassium, different selectivity enhancement techniques have been examined. A
