The standard material is mainly used for the respective ingredients in food, health, environment, agriculture, residue testing process analysis and detection instrument calibration, evaluation of analytical methods and quality control.
A sample preparation
The purity of standard materials using accurate valuation of HCB pure as raw materials, using methanol as solvent, the weight - volumetric method accurate preparation.
Second, traceability and valuation methods
This standard substance to formulate a value as the standard value of the standard concentration of a substance, material standards and quality control samples prepared from control by gas chromatography (GC-ECD) ratio calculation, verification formulated value. By using the method of preparation to meet the requirements of the metrological characteristics, measurement methods and measuring equipment to ensure traceability of reference materials.
Third, the magnitude and characteristics of Uncertainty
