ISO 5985 - Determination of Insoluble Ash in Hydrochloric Acid in Feed

The ISO 5985 standard specifies two procedures in animal feed for the determination of ash insoluble in hydrochloric acid. Procedure details are as follows:

- Procedure A; Applicable to simple organic animal feeds and compound feeds. The sample is incinerated and the ashes are boiled in hydrochloric acid and the insoluble residue is filtered and weighed.
- Procedure B; Applies to minerals, mineral mixtures and compound feedstuffs with ash insoluble in hydrochloric acid exceeding 1% (mass fraction). It is treated with hydrochloric acid and the resulting solution is filtered. The residue is ashed and then processed as in method A.

With the Determination of Insoluble Ash in Hydrochloric Acid, it is aimed to determine the amount of inorganic residue present in a sample. You can contact Nanolab Food Analysis Laboratory for the determination of ash insoluble in hydrochloric acid.
