Dispersion medium
15 minChoose a dispersion medium matching the sample refractive index
💡 Tip Usually water or ethanol
⚠️ Caution Medium must be clean

2
Calibration & background
15 minMeasure blank dispersion as background and calibrate with standard particles
💡 Tip Background should be low and stable
⚠️ Caution Periodically verify with standard particles

3
Disperse & load
20 minDisperse the sample in medium by ultrasonication and add to the cell
💡 Tip Use ultrasonication to prevent agglomeration
⚠️ Caution Keep obscuration moderate to avoid multiple scattering

4
Measurement & acquisition
20 minRun the measurement and record the scattering intensity distribution
💡 Tip Repeat for stable results
⚠️ Caution Avoid air bubbles

5
Result & report
20 minCalculate D10/D50/D90 and issue a size distribution report
💡 Tip Report D50 and other percentile sizes
⚠️ Caution Note dispersion conditions and refractive index

⚠️ 5 Common Beginner Mistakes
- ① High obscuration causing multiple scattering bias
- ② Insufficient dispersion with agglomeration
- ③ Wrong refractive index parameters
- ④ Bubbles in medium interfering
- ⑤ Non-representative sampling
❓ FAQ
+What does D50 mean?
Median size; 50% of particles are smaller.
+Why dispersant?
Prevents agglomeration to get true distribution.
+Good obscuration?
Generally 10–20% is appropriate.
