摘要：

The sample preparation of real world water samples for potentiometric determinations is often time and labor consuming. Therefore sample preparation systems were developed for the determination of water hardness and nitrate concentrations in drinking water and well water. The systems allow the adjustment of the ionic strength and removal of interfering ions. The sample preparation agents required are fixed by using a disposable sample preparation disk. The system was tested by analyzing real water samples and the results were compared to those obtained by using reference methods.
