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 …

The opto-acoustic determination of low absorptions has been applied to the assay of small
amounts of nonfluorescent absorbers In liquids. The output of an argon ion laser at 488 and …

Laser induced photoacoustic spectroscopy (LIPAS) has been confirmed as an analytical
tool, suitable for the determination of inorganic and organic species in aqueous and organic …

A quantitative investigation of the photoacoustic (PA) signal amplitude on the exponential
optical absorption coefficient, ί (= absorbance X (In 10)/cm), In thermally thick liquid samples …

In previous studies" z, we developed photoacoustic spectrometry coupled with a total
internal reflection technique (TIR-PAS) with the aid of a direct coupling method in which a …

The temporal photoacoustic response of dissolved and dispersed absorbers (glucose and
colloidal graphite) in aqueous systems have been studied by use of a time resolved …

Pulsed laser photoacoustic spectroscopy has been used as the basis for sensing analytes in
aqueous systems. The spectra obtained with the photoacoustic system are significantly …

A new photoacoustic sensor system for on-line monitoring of highly concentrated and optical
opaque liquid samples is presented. The dyeing of textiles is performed with highly …

In this article, a photoacoustic technique, excited by a pulsed diode laser, is used in a study
of optically absorbing and scattering liquids. The article discusses the effects of optical …
