When light is scattered from a solution or a suspension, it undergoes random changes in intensity. This phenomenon helps us to determine the size of the particles that scatter the light. This is the ...

Nanoparticles of increasingly smaller particle size and various material compositions are being developed for the pharmaceutical, biomedical, electronics, optoelectronics, energy, catalyst and ...

Research was conducted to determine the optimum laser diffraction-based particle sizing dispersion method for Domperidone API. This study employed the Bettersizer 2600 - an automatic laser diffraction ...

The “tail” of a particle size distribution references the particles that are several standard deviations removed from the mean of the standard Gaussian distribution. Figure 1 demonstrates the ...

Dynamic light scattering techniques are used to determine particle size distributions of protein therapeutic formulations. In DLS-based measurement, scattering intensity changes are associated across ...

The authors present a simple and material-sparing approach for estimating the powder-flow performance of previously uncharacterized single-component bulk powders when only particle-size distribution ...

Conventional DLS instruments use a detection angle of 90°. The concentration limit of instruments using such optics is very low, as multiple scattering effects need to be eliminated. Multiple ...

Visual mapping can provide a particle-size distribution estimate. Q. Is there a clever way to directly measure drug/API particle size distribution in a tablet blend/granulation, assuming API has very ...

E-cigarette use is rising, particularly among young adults and teens. Recent illnesses and deaths attributed to vaping have caused intense scrutiny of the chemicals in e-liquids and vapor, but little ...
