标准值:100μg/mL,扩展不确定度(K=2):3%
标准值的不确定度主要由原料纯度,称量,定容以及均匀性,稳定性等不确定度分量合成。
This standard substance is mainly used for measuring instrument calibration, analysis method evaluation and quality control, as well as the content determination and residue detection of corresponding components in the fields of food, hygiene, environment and agriculture. It can also be used for value traceability or as a standard stock solution. Dilute and prepare various standard solutions for work, etc.
1. Sample preparation
This standard material is made of pure thidiazuron with accurate purity as the raw material, HPLC grade methanol as the solvent, and accurately prepared by the gravimetric method. Thidiazuron (alias: Deyeling), English name: Thidiazuron, CAS No.: 51707-55-2 2.
2.Traceability and valuation method
This standard material takes the prepared value as the standard value, and uses high performance liquid chromatography-diode array detector (HPLC-DAD) to compare this batch of standard materials and quality control control samples to verify the prepared value. Through the use of preparation methods, measurement methods and measuring instruments that meet the requirements of metrological characteristics, the traceability of the value of the reference material is guaranteed.
3. Characteristic value and uncertainty
Standard value: 100μg/mL, expanded uncertainty (K=2): 3% The uncertainty of the standard value is mainly composed of raw material purity, weighing, constant volume, uniformity, stability and other uncertainty components.
