Acetochlor Solution in Methanol (C007B-016036)

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.Sample PreparationThis standard substance is made of pure Acetochlor with accurate purity as raw material, HPLC grade methanol as solvent, and accurate preparation by weight-volume method.Traceability and valuation methodThis standard material takes the prepared value as the standard value, and uses GC-MS to compare the 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.Characteristic value and uncertaintyStandard value:100μg/mL,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.Uniformity inspection and stability inspectionAccording to JJF1343-2012 [General Principles and Statistical Principles for Determining Standard Material Values], the samples after subpackage are randomly sampled, the solution concentration is tested for uniformity and stability. The results show that the standard material has good uniformity and stability.The quality value of this standard material is valid for 24 months from the date of setting the value. The development unit will continue to track and monitor the stability of the standard material. If the value changes within the validity period, the user will be notified in time.Packaging, transportation and storage, use and precautions1. Packaging: This standard substance is packaged in borosilicate glass ampoule, about 1.2mL/piece, please refer to the pipette volume when pipetting or diluting.2. Transportation and storage: ice bag transportation, avoid squeezing and collision during transportation; store under refrigerated and dark conditions.3. Use: Equilibrate at room temperature (20±3℃) before unpacking and shake well. Once the ampoule is opened, it should be used immediately. It cannot be used as a standard substance after being sealed again.
