Introduction
1. Standard Overview
GB/T32341-2015 "Azoxystrobin Technical Material" is a national standard formulated for the technical requirements and test methods of azoxystrobin technical material, and is applicable to azoxystrobin technical material composed of azoxystrobin and impurities generated during its production.
2. Comparison of standard frameworks
| Standard dimensions | GB/T32341—2015 | International integration | Implementation requirements |
|---|---|---|---|
| Technical indicators | Mass fraction of azoxystrobin ≥ 97.0%, moisture ≤ 0.5%, pH value 5.0~8.0, acetone insoluble matter ≤ 0.2% | In line with ISO international standards | Mandatory implementation |
| Detection methods | Gas chromatography, liquid chromatography, Karl Fischer method | Consistent with internationally accepted methods | Laboratories must be equipped with appropriate equipment |
| Safety requirements | Low-toxic fungicides, operators must wear protective equipment | Comply with international pesticide management standards | Manufacturers must be equipped with safety facilities |
3. Interpretation of technical requirements
3.1 Technical indicators of azoxystrobin technical
The mass fraction of azoxystrobin technical is required to be high, reaching more than 97%, and the moisture, pH value and acetone insoluble matter are strictly controlled. The setting of these indicators ensures the stability and effectiveness of azoxystrobin products.
3.2 Detailed explanation of detection method
Gas chromatography: It uses H
P-1701 capillary column and hydrogen flame ionization detector for separation and determination, which is efficient and accurate.
Liquid chromatography: It uses a stainless steel column with C18 filler and a UV detector to separate and determine at a wavelength of 254nm, which is suitable for the mass fraction detection of azoxystrobin.
4. Implementation suggestions
To ensure the effective implementation of GB/T32341—2015 standard, it is recommended that:
- Manufacturers need to be equipped with advanced detection equipment and calibrate them regularly.
- Operators need to receive professional training and be familiar with detection methods and safety protection measures.
- Strengthen quality control and establish a complete quality traceability system.
