Metribuzin in Methanol (C007B-226694)

ApplicationThis standard substance is mainly used for measuring instrument calibration, analytical method evaluation and quality control, and the determination of corresponding components and residue detection in the fields of food, sanitation, environment and agriculture.Sample PreparationThis standard substance is prepared by using the purity standard substance Metribuzin as the solute, methanol as the solvent, and the weight-volume method in a clean laboratory at room temperature of 20±3°C.Characteristic value and expanded uncertaintyComponentStandard valueExpanded uncertainty (k=2)MatrixMetribuzin100μg/mL3%methanolIt is mainly synthesized by the uncertainty of raw material purity, weighing, constant volume, uniformity, and long-term stability.Packaging, storage and usePackaging: This standard material is packaged, and the specification 1.2mL should be protected from shattering when carried or transported. Storage and use: Keep it under refrigerated airtight and protected from light. Before use, it should be balanced at room temperature (20±3℃) and shake well to ensure uniformity. Once the ampoule is opened, it should be used immediately. It cannot be used as a standard substance after being re-sealed. Strictly prevent contamination during use.
