Description
|
SRM 695 - Trace Elements in Multi-Nutrient Fertilizer This Standard Reference Material (SRM) is intended primarily for use in the evaluation of techniques employed in the analysis of multi-nutrient fertilizer materials and materials of a similar matrix. The material consists of urea, diammonium hydrogen phosphate, calcium carbonate, potassium chloride, potassium nitrate, and potassium magnesium sulfate, and various other metal sulfates. The material was ground and shipped to NIST where the material was jet-milled, blended, and bottled by C. Fales of the Measurement Services Division.
One unit of SRM 695 consists of approximately 70 g of jet-milled fertilizer. keywords: environmental materials , industrial materials , agro-chemicals, trace elements , heavy metals
