Sample Categorization
For best results, it is important to determine the correct ratio of Diatomaceous Earth (DE) to sample. Before using
your ANKOM
HCl
Hydrolysis System for production testing, it is recommended that you categorize your samples
into types and determine the standard amount of DE needed for each sample type. The following information is
from testing done in the ANKOM lab. This information is meant to help you categorize your own samples.
