Information

Question

What is the particle size of your sodium chloride products? I do not see this information on the Product Specification sheet or Certificate of Analysis.

Answer

Particle size may not be part of the product specifications and may not be routinely tested by Avantor Performance Materials. However, we expect the particle size distribution properties to be as per the table below for the following Avantor Performance Materials products:
