This standard substance is mainly used in the fields of food, hygiene, environment, agriculture, etc. The content of corresponding components, residual detection and analytical instrument calibration, analysis method evaluation and quality control in the detection process.
Sample Preparation
This standard material is made of pure betaine with accurate purity as the raw material, methanol as the solvent, and accurately prepared by the weight-volume method in a clean laboratory at room temperature of 20℃±3℃.
Traceability and valuation method
This standard substance takes the prepared value as the standard value, and uses high performance liquid chromatography-tandem mass spectrometry to verify the value. Through the use of preparation techniques, measuring 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 uncertainty
Number | Name | Standard value (μg/mL) | Uncertainty(%) (k=2) |
B265660 | Betanin Solution in Methanol | 100 | 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 inspection
With reference to the technical specifications of the national "Class 1 Standard Substances", random sampling is carried out on the subpackaged samples. High performance liquid chromatography-tandem mass spectrometry (HPLC-MS) was used to test the uniformity and stability of the solution concentration. Test result: the uniformity meets the F test rule, and the stability is well investigated.
This standard substance has a validity period of 2 years from the date of setting the value. The development unit will continue to track and monitor the stability of the standard substance. If there is any change in the value within the validity period, the user will be notified in time.
Packaging, transportation and storage, use and precautions
1. 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.
