Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:

Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Reference:
Composition 0
Qualifier:
no guideline followed
Principles of method if other than guideline:
A particle size (PS) distribution of F-2200 LOT # 290110772 was measured using Mastersizer 2000 (Malvern Instruments). 1 gr. sample was added to 10 ml of 4% Sodium Dodecyl Sulphate aqueous solution. A suspension obtained was added to water and then sonicated for 3min.

Conclusions:
A particle size (PS) distribution was measured using Mastersizer 2000 (Malvern Instruments). PS distribution was found to be:
10% of the volume distribution is below 10.9 µm (D 10 = 10.9 µm)
50% of the volume distribution is below 128.2 µm (D 50 = 128.2 µm)
90% of the volume distribution is below 508.4 µm (D 90 = 508.4 µm)
Executive summary:

A particle size (PS) distribution was measured using Mastersizer 2000 (Malvern Instruments). PS distribution was found to be:

10% of the volume distribution is below  10.9 µm (D 10 = 10.9 µm)

50% of the volume distribution is below 128.2 µm (D 50 = 128.2 µm)

90% of the volume distribution is below 508.4 µm (D 90 = 508.4 µm)
