Abstract

This paper reports on novel solutions to problem of in situ, real-time measurements in water without chemical enrichment steps. We have developed a photoacoustic and three miniaturized photothermal systems in our laboratory, allowing the construction of microstructured, miniaturized, adjustment-free and user-friendly analytical microprobes. The new systems are: photoacoustic spectroscopy, photothermal interferometry, thermal lensing and photothermal deflection spectroscopy. The determined analytes are pesticides, polycyclic aromatic hydrocarbons, textile dyes and iron in natural, ground and drinking water.
