Raw Materials USP Zinc Oxide Assays

Project Description

Contract Analytical Chemistry Laboratory needed for USP zinc oxide assays on a raw material. This raw material is a zinc oxide with coating.We need to realize this analyse based on the USP method [zinc oxyde monograph] that is why we would like to realize assay by Ion Chromatography.Our raw material is a coated ingredient, our supplier inform us that we need to remove coating before analyzing.He provided us following information : This can be done by a method called Loss On Ignition (LOI), which basically burns off the silicone coating from raw material. After this procedure, the powder needs to be cooled in a desiccator. When the powder reached an approximate standard room temperature (25°C), one would be able to perform the assay on the product - based on the USP method.

Please send us a quotation.
