Walter B.Wilson and Lance C. SanderChemical Sciences DivisionMaterial Measurement LaboratoryNational Institute of Standards and Technology[1]Gaithersburg, MD  20899This presentation details some of the steps used at NIST to prepare botanical reference materials and control materials.  The procedures shown are generalized to provide examples of laboratory operations and are not recommendations for specific methods.  The example shown is for a hemp-based quality control material, but similar procedures are used for other botanicals.  Processing steps include grinding, sieving, mixing, and packaging.-------------------------------[1]Contribution of the National Institute of Standards and Technology.  Not subject to copyright.
