In many relevant industrial applications, UV− vis online process monitoring is hampered by
light scattering and opacity of the samples, whereas diluted and filtered samples are rarely …

The application of laser-induced photoacoustic spectroscopy (LIRAS) to the determination of
ultra trace particles in sus-pension was attempted. Using BaS04 particles produced …

Laser-induced photoacoustic spectroscopy has been applied to the determination of
