Herbicides Residue Testing Service

The problem of herbicide residues and their potential to damage crops is increasing. And the residual herbicide may endanger the health of contacts. Therefore, it is necessary to accurately assess the presence of residues.

Herbicides applied to the soil may be partially decomposed by microorganisms and lose their activity, while some are still toxic and exist in the soil solution. After being absorbed by plants, most of the herbicides will be transported to the target site to exert their biological toxicity for weeding, and some of them will be decomposed or inactivated due to metabolism in the plant, or turned into non-toxic. Physical and chemical testing can be used to detect the amount of herbicide residues in soil solutions or plants. Plant bioassays can be used to screen to determine whether there are herbicide chemicals that may inhibit the normal development of sensitive plants, and to determine the amount of pesticide residues that are truly active. Therefore, the detection of the amount of herbicide residue can be used as a reference for application, and it can also prevent people from having excessive residues in food to ensure human health.

Alfa Chemistry has developed rapid detection technologies suitable for multi-residue herbicides, and can provide herbicides residue testing services for manufacturers, enterprises, and government organizations. We strictly abide by the quality assurance/quality control plans and regulatory requirements of each country and region to provide you with support. Including but not limited to the following standards and methods: ISO, FDA, AOAC, EU regulations, LFGB, DGCCRF, JFSL, GB/T and SN.

Herbicides Residue Testing Service Technology Platform

Physical and chemical testing methods

➢ Sample preparation:

• Solid phase extraction (SPE)
• Liquid phase extraction (LPE)
• Supercritical fluid extraction (SFE)

➢ Clean up:

• Dispersive SPE.
• Gel Permeation Chromatography

➢ Sample detection technology:

• Gas chromatography with electron capture detector (GC-ECD): ECD is the most commonly used detector for the determination of herbicide residues in food samples.
• Gas chromatography-mass spectrometer (GC-MS).
• High-performance liquid chromatography-mass spectrometry (HPLC/MS/MS).

Bioassay

This method is used to determine the reaction of biological materials to chemical agents. Its main purpose is to qualitatively determine whether there is an active chemical agent. Sometimes it can be used to quantify the amount of drug.

At Alfa Chemistry, our analytical scientists are experienced in herbicides residue testing service. After communicating with you about the testing scheme, we will implement it within a quick turnaround time and provide you with an analysis report.
