Abstract
The construction techniques and behaviour of tubular potentiometric detectors based on homogeneous crystalline membranes to be used in flow injection manifolds are reported. Tubular detectors for chloride and sulphide anions were prepared using pressed membranes with silver salts. The results of the assessment of their behaviour against that of the conventional selective electrodes using the same membrane are reported. Data obtained with FIA manifolds with tubular detectors in the determination of chloride and sulphide anions in natural and waste waters are also presented.
