Advantages of the Frequency Power Spectrum Method


Published on

If you’re using dynamic light scattering (DLS) for the measurement of your nano-particles, you may be familiar with the photon correlation spectroscopy (PCS) method. Although PCS is a widely used DLS method of measurement, there is a superior method.

Microtrac’s proprietary approach to DLS, the frequency power spectrum method (FPS), overcomes the limitations of PCS. Heterodyne FPS gathers data in higher resolution than PCS. Having the detector set to 180° allows to measure in higher concentrations, and to even go on-line. The Microtrac FPS method effectively allows to accurately measure from sub-nanometer to several microns across the widest concentration range on the market.

Join us as we go in depth on dynamic light scattering and discuss topics such as:

Frequency Power Spectrum
Photon Correlation Spectroscopy
Reference Beating
Heterodyne Detection vs Homodyne Detection
and more!

Joining us for this webinar is special guest, Dermot Brabazon from Dublin City University. He will present comparison data and talk about his experience using Microtrac’s Nanotrac Flex.

Microtrac, Inc. is a particle characterization instrumentation company dedicated to particle science and customer satisfaction. Microtrac released the first commercially available particle size analyzer using laser diffraction. We have over 40 years particle characterization experience and technology.
