Abstract
The use of an optothermal window (OW) was proposed for the direct (no need for sample preparation) spectroscopic, non-destructive measuremen t of SO42- in water at 1078 cm(-1). The presently determined limit of detection (LOD) of 1 mmol/L is comparable to that provided by CO2 lase r photoacoustic spectroscopy, but about one order of magnitude superio r to that obtainable by the ATR method.
