The detector allows the evaluation of the analytical response characteristics of the poly(vinyl chloride)-based membranes to be done in the flow injection analysis mode. Such ion-selective electrode membranes, containing either ion-exchangers or neutral carrier type of electroactive component, in conjunction with appropriate plasticizing solvent, and sometimes other membrane additive as was the case for paraquat selective membranes, can be conveniently applied to the detector assembly. Utilization of the flow-through detector allows studies on the sensing of the antimalarial drug, quinine, and the herbicide, paraquat, to be conducted conveniently. Details of the flow-through detector and its performance when used for the determination of the respective ion of interest under different matrices are described. © 2000 John Wiley & Sons, Inc.

This method is based on the reaction of luminol with hydrogen peroxide catalysed by cobalt(II) in an alkaline medium. Sodium dodecyl sulphate (SDS) was used as sensitizer agent, and its presence greatly accelerated the reaction and enhanced the CL intensity. An FI stopped-flow technique was introduced to the CL reaction to increase sensitivity. Optimal conditions for the chemiluminescence reaction were examined. The sampling frequency was 50 hr−1 for injection volumes of 100 µL. The detection limit of hydrogen peroxide, defined as 3 times the standard deviation of the blank, was 0.5 nM in high purity water, and the working linear range was 1 to 105 nM. For the determination of 15 nM and 52 nM hydrogen peroxide, the relative standard deviations were 2.8 and 2.3% respectively (n = 11). The method has been applied to the determination of hydrogen peroxide in natural water samples. © 2000 John Wiley & Sons, Inc.

Both the pumps and the valve are driven by stepper motors with photoswitch position detection. By movement coordination of the pumps and the valve, no separate waiting time is necessary for the syringe to be refilled or discharged, and the leakage problem of the valve is also alleviated. The analyzer can be operated in two modes, flow-injection-analysis mode, into which most current FIA methods developed with peristaltic pumps can be easily adapted, and microtitration mode, with which major components in a sample can be titrated quickly, accurately, and in a microchemical way. To demonstrate, the analyzer was employed both for the determination of trace amounts of tungsten in the raffinate of ammonium paratungstate (APT) processing with FIA mode and for the determination of caustic hydroxide in the industrial production of aluminum oxide with microtitration mode. The typical sampling rates are 60 and 45 samples h−1 for FIA mode and titration mode, respectively. © 2000 John Wiley & Sons, Inc.
