Abstract

A novel tangential photopyroelectric (PPE) cell for liquids is described in which the excitation laser beam is position-modulated. As a result, only the thermal wave is modulated and the background signal due to scattered light is suppressed by more than 50 times. The application for water pollution monitoring shows a detection limit of 1 mmol/m3 ammonium ion in water.
