Acoustic resonance spectroscopy

<p>Acoustic resonance spectroscopy (ARS) is a method of <a href="/facts/Spectroscopy/mj71FuNK">spectroscopy</a> in the <a href="/facts/Acoustics/2GpQUymy">acoustic</a> region, primarily the sonic and <a href="/facts/Ultrasound/31Pa5IH9">ultrasonic</a> regions. ARS is typically much more rapid than <a href="/facts/High-performance_liquid_chromatography/UNT9jPp0">HPLC</a> and <a href="/facts/Infrared/44XdJNcc">NIR</a>. It is non destructive and requires no sample preparation as the sampling waveguide can simply be pushed into a sample powder/liquid or in contact with a solid sample. 
</p><p>To date, the AR <a href="/facts/Acoustic_spectrometer/wxfPggE8">spectrometer</a> has successfully differentiated and quantified sample analytes in various forms; (tablets, powders, and liquids). It has been used to measure and monitor the progression of chemical reactions, such as the setting and hardening of <a href="/facts/Concrete/K6whGVNx">concrete</a> from <a href="/facts/Cement/VfDMkk12">cement paste</a> to solid. Acoustic spectrometry has also been used to measure the volume fraction of <a href="/facts/Colloid/9EVucqND">colloids</a> in a <a href="/facts/Dispersion_medium/I3PtFGsj">dispersion medium</a>, as well as for the investigation of physical properties of <a href="/facts/Colloidal_dispersion/9EVucqND">colloidal dispersions</a>, such as aggregation and <a href="/facts/Particle/JHKr2w6h">particle</a> size distribution. Typically, these experiments are carried out with <a href="/facts/Sinusoidal/mD1CB09M">sinusoidal</a> excitation signals and the experimental observation of signal <a href="/facts/Attenuation/XP4vX360">attenuation</a>. From a comparison of theoretical attenuation to experimental observation, the particle size distribution and aggregation phenomena are inferred.
