Introduction
National Standard of the People's Republic of China GB/T 33809—2017
Technical Requirements and Test Methods for Thiamethoxam Technical Material
| Item | Indicator |
|---|---|
| Thiamethoxam mass fraction/% | = 98.0 |
| Dimethylformamide insoluble matter/% | ≤ 0.3 |
| Water/% | ≤ 0.5 |
| pH value | 5.0~8.0 |
1. Background of standard formulation and analysis of technological evolution
Background of standard formulation:As an important pesticide ingredient, the quality and technical requirements of thiamethoxam technical directly affect the safety and effectiveness of agricultural production. The formulation of GB/T 33809-2017 is based on the actual needs of agricultural production and aims to standardize the quality control and detection methods of thiamethoxam technical.
Technical evolution analysis:With the technological progress of the pesticide industry, the production and detection methods of thiamethoxam are also being continuously optimized. This standard introduces high performance liquid chromatography (HPLC) and infrared spectroscopy (IR) to ensure the accuracy and reliability of detection.
2. Comparative analysis of standard framework
The following is a comparison of the main dimensions of GB/T 33809-2017 and related standards:
| Dimension | GB/T 33809-2017 | Comparison standard | Difference description |
|---|---|---|---|
| Quality indicator | Thiamethoxam ≥98.0% | - | New high purity requirements |
| Detection method | Combination of HPLC and IR | Single chromatography | Improve detection accuracy |
3. Implementation suggestions
Manufacturers:
- Strictly follow the standard requirements for raw material procurement and production control
- Establish a complete quality traceability system
- Carry out internal training regularly to ensure that technical personnel are familiar with new methods
Testing institutions:
