Introduction
1. Standard background and technical evolution analysis
GB/T 22620-2023 Bifenthrin EC is a comprehensive revision of the 2008 version. This revision introduces a number of new technical requirements, including liquid chromatography as an arbitration detection method, the addition of a persistent foaming control item, and a thermal storage stability test. These changes reflect the pesticide industry's higher requirements for product quality and stability.
2. Comparative Analysis of Technical Indicators
| Item | 25g/L Specification | 100g/L Specification |
|---|---|---|
| Bifenthrin Mass Fraction/% | 2.8±0.28 | 11.0±0.86 |
| Bifenthrin Mass Concentration (g/L) | 25±3 | 100±18 |
| Water/% | ≤3.0 | |
| pH value | 4.0~7.0 | |
3. New items and implementation suggestions
Persistent foaming control:The standard has added a new persistent foaming index (≤40mL) to ensure that emulsifiable concentrate products will not produce excessive foam during use, affecting the application effect.
Hot storage stability test:The product is required to have a mass fraction of bifenthrin of no less than 97% of the original value after high temperature storage, while maintaining the emulsion stability and pH value in compliance with the requirements. This project is tested by combining liquid chromatography and gas chromatography to ensure data accuracy.
Implementation suggestions:Manufacturers should establish a sound quality control system, focus on monitoring new indicators, and conduct regular type inspections (at least once a quarter). At the same time, it is recommended to use high-precision instruments such as high performance liquid chromatograph and gas chromatograph for arbitration testing.
