Introduction
Interpretation of GB/T32889-2016 Standard
| Technical Requirements | Standard Provisions | Practical Significance |
|---|---|---|
| Detection Method | Gas Chromatography-Mass Spectrometry (GC-MS) | Ensure High Sensitivity and Accuracy of Analysis |
| Extraction Solvent | Toluene-Methanol (10+1 Volume Ratio) | Optimize Extraction Efficiency and Reduce Impurity Interference |
| Derivatization Reagent | N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) | Improve the detection sensitivity and stability of the target |
Standard formulation background and technology evolution analysis
Background:With the widespread use of brominated flame retardants in electronic and electrical products, tetrabromobisphenol A (TBBPA) as a typical representative, its harm to human body and environment has gradually attracted attention. This standard aims to standardize the detection method to ensure product quality and safety.
Instrument requirements
- Gas chromatography-mass spectrometry (GC-MS): It must meet high sensitivity and resolution to ensure accurate detection of the target.
- Microwave extractor: It is used to efficiently extract the target compound in the sample.
- Analytical balance: The precision requirement is 0.1mg to ensure the weighing accuracy.
Implementation suggestions
- Sample preparation: Ensure that the sample is crushed evenly and the particle size is controlled below 1mm to avoid affecting the extraction efficiency.
- Extraction conditions: Strictly control the temperature and time of microwave extraction to prevent sample decomposition or volatilization.
- Derivatization reaction: Accurately control the amount of BSTFA added and the reaction time to ensure the derivatization effect.
- Instrument calibration: Regularly calibrate the GC-MS system to ensure the accuracy and reliability of the test data.
