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 Preparation
This standard material uses pure tetrabutylene with accurate purity as raw material, chromatographic grade methanol as solvent, and is accurately prepared by gravimetric-volume method in a clean laboratory at room temperature 20℃±3℃.
Terbuthylazine, English name: Terbuthylazine, CAS: 5915-41-3
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) Relative expanded uncertainty (%) (k=2)
T265653 Terbutaline in toluene 1000 3
| Number | Name | Standard value(μg/mL) | Relative expanded uncertainty(%)(k=2) |
| T265653 | Terbuthylazine 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
According to JJF 1343-2012 "General Principles and Statistical Principles for Determining the Value of Reference Materials", random samples were taken of the subpackaged samples, and liquid-phase mass spectrometry was used to inspect the uniformity and stability of the value. The results show that the standard material has good uniformity and stability.
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 in freezing 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.
