Laser Diffraction, Particle Size Analysis Frequently Asked Questions
Do you know what the most frequently asked questions by customers using particle size analyzers are?
Today, we present the most frequently asked questions and answers.
What does Dv10 mean?
Dv10 refers to the 10th percentile of the cumulative volume distribution. This indicates that 10% of the sample’s volume is below this size, and it is used to track changes in the finest particles within a sample. In general, the Dv10, Dv50, and Dv90 percentile values are automatically reported by the software.
How much sample should be used for particle size analysis?
We use ‘obscuration’, which is the amount of light blocked or scattered by particles, as a method to measure particle concentration in particle size analyzers. The recommended range of obscuration varies depending on the particle size, and it is differently applied in wet and dry dispersion. For wet measurements, you can conduct obscuration titration to determine the appropriate obscuration range.
