Particle Size Distribution (Alpine Granulation) Test

Price of the test:

$40 per sieve

Acceptable Matrices:

Powders and particulates

Unacceptable Matrices:

Liquids, particle sizes > 37 micrometers

Limit of Detection:

US Standard sieves from #10 to #400, with sieve openings from 2000 to 37 micrometers.

Sample Size Requirements:

25 grams

Equipment:

Alpine Air Jet Sieve

Reportable Units:

% retained on each sieve

Turn Around Time:

7-9 Business days

Is Rush Available?

Yes

Method Reference:

Internally Developed Method

Method Description:

The Alpine Air Jet sieve tester measures the particle size profiles in powdered ingredients and products. The Alpine uses an air jet to lift particles from the surface in conjunction with a vacuum to draw them back down and through the sieve. This action prevents sieve binding.

Information Required by Submitter:

Please provide the sieve sizes to be tested, either US Std sieve numbers or particle size range to be covered (micrometers, millimeters, or inches).

Additional Information:

This is the optimal test to use on products that may bind to a sieve.
