Particle size distribution (Granulometry)

Link to relevant study record(s)

Reference

Endpoint:

particle size distribution (granulometry)

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Reason / purpose for cross-reference:

reference to same study

Principles of method if other than guideline:

Sieving and light scattering. Calculated the percentage of particles that were less than 105 µm. The particles less than 105 µm were analysed for particle size distribution using a Beckman Coulter LS 230 Particle Size Analyzer.

GLP compliance:

yes

Type of method:

sieving

Type of distribution:

volumetric distribution

No.:

#1

Size:

< 105 µm

Distribution:

0.78 %

Granulometry: 0.78% < 105 µm

< 0.2% of total weight < 13.56 µm

 

Particle Size Distribution of Particles less than 105 µm  

Volume %	Particle Diameter µm Greater Than
10	21.23
25	19.63
50	17.00
75	13.56
90	7.148

Conclusions:

0.78% < l05 µm

Executive summary:

Determination of granulometry: Accurately weighed a l05 µm sieve and an empty pan. Accurately weighed approximately 5 g of test substance into the sieve. Place sieve and pan on a sieve shaker and shook for 5 minutes. Re-weighed the sieve and the pan. Calculated the percentage of particles that were less than l05 µm. The particles less than l05 µm were analysed for particle size distribution using a Beckman Coulter LS 230 Particle Size Analyzer.

Granulometry: 0.78% < l05 µm
