Thank you. What is the minimum concentration of the sample required when we are using powders.Could you please elaborate more on sample preparation of powder solutions for accurate DLS measurements.
Hello, Sai. In order to measure powders by DLS you’ll need to find a suitable solvent to disperse them in. For more information on dissolution of dry powder samples you can refer to our sample preparation guide: www.brookhaveninstruments.com/guide-for-dls-sample-preparation/ The minimum concentration is going to depend heavily on the material. The larger the difference between sample and solvent refractive index, the lower the minimum viable concentration will be.
Thanks because of your nice explanation,
is it possible write the notes?
2:25 He says it so fast. The syringe is used to filter the KNO3.
thank u soooo much! details are so good
