Methods Type: 
Generic Methods
Key data
Number: 
127
Analyte: 
Particle Size (Andreasen Pipette Method)
Matrix: 
Cereal flours
Year of Approval: 
1976
Scope: 
Applicable to cereal flours.
Principle: 
The Andreasen method assumes that particles will sediment at a rate dependent on their size and further assumes the validity of Stoke´s Law in this respect.
