At our company, we pride ourselves on providing a high quality product to our customers. To ensure that our products meet the highest standards, we have a team of quality control experts who test and inspect our products before they are shipped out.Our quality control service includes a thorough inspection of our products to ensure that they meet all safety and quality standards. We also pay close attention to our manufacturing process to ensure that our products are made to the highest standards.

Inspection of Quality

The Quality Management Department of Zhejiang Heben Pesticide & Chemicals Co., Ltd. was founded in 1995. After more than 20 years of efforts and development, we have built a professional and technical quality inspection team that can provide full component analysis of active pesticides and pesticide preparations. The Quality Management Department mainly consists of two parts: the Analysis and Research Center and the Quality Inspection Center.

The Analysis and Research Center

The Analysis and Research Center was established in 2014 with an investment of more than 1.4 million in accordance with the requirements of the GLP laboratory. It is a platform for analysis, testing and scientific research innovation. The center system covers a laboratory area of about 430 square meters, with 100 sets (sets) of facilities and equipment in use. Besides, the fixed assets of equipment are more than 710 thousand dollars.

The centre has 11 GLP system personnel at present, including 2 with a master’s degree, 7 with a bachelor’s degree, 1 with a college degree, and 1 with a technical secondary school degree. There are 2 quality assurance personnel and 2 project leaders, all of whom are professional technical backbones with plentiful experience in analysis and testing.

Hardware Resources

Maintaining and improving product quality is essential to remaining competitive in the market. As a modern scientific and technological enterprise, Heben Analysis and Research Center possesses the most up-to-date testing equipment necessary for modern pesticide technology enterprises, as well as a standardized technical team.

Agilent 7890A/5975C GC-MS

GC-MS is a tool that joins a gas chromatograph with a mass spectrometer, and it is commonly used to separate and identify complex components. GC-MS has the high resolution of GC and the high sensitivity of mass spectrometry, making it a sound choice for the qualitative and quantitative determination of drugs and metabolites in biological samples.


LC/MS refers to an instrument that combines a liquid chromatograph and a mass spectrometer (ionic hydrazine). LC/MS is widely used for the separation and identification of large molecular weight products that are difficult to gasify. The structure of compounds is gradually analyzed by the secondary and tertiary fragmentation of ion fragments.


UHPLC (Ultra High Performance Liquid Chromatography) is a more recent, more potent type of liquid chromatography that produces extremely high-resolution separations. UPLC technology, being a highly stable, reliable and replicable separation technology, has been utilised successfully in a multitude of demanding analytical fields by major laboratories globally.


Ion chromatography is a chromatography method used to separate and quantify ions. The ion chromatograph is most commonly used for the detection of standard anions and cations, especially for the qualitative and quantitative detection of Counter ions of pesticide products with Paired ions. The ion chromatograph has high separation efficiency, and can be operated under relatively low ionic strength conditions, making it also suitable for the determination of some weakly acidic or weakly alkaline substances.
