Multi-Residue Pesticide Screening by GC-MS
In the realm of agricultural and forestry testing, ensuring food safety and environmental sustainability is paramount. The presence of pesticides in crops can have significant implications for human health and ecological balance. To address this critical need, our laboratory offers a robust service: Multi-Residue Pesticide Screening by GC-MS (Gas Chromatography-Mass Spectrometry).
GC-MS is a powerful analytical technique capable of detecting multiple pesticide residues simultaneously in crops. This method ensures comprehensive screening, providing accurate and reliable results that comply with international standards such as ISO 17025, EN 16438, and ASTM D7289.
The process begins with the collection of representative crop samples from various locations within a field or orchard. These samples are then prepared according to standard protocols, ensuring they represent the true composition of the crop. Post-sample preparation, the extracts undergo several purification steps to remove interfering compounds and concentrate the target analytes.
Once purified, the extracts are injected into the GC-MS system. The gas chromatograph separates the components based on their volatility and polarity, while the mass spectrometer identifies each compound by its unique fragmentation pattern. This tandem approach allows for precise quantification of multiple pesticides simultaneously.
The results of our multi-residue pesticide screening service are presented in a detailed report that includes all detected residues along with their concentrations. Our team of experts ensures that these reports meet the highest standards of accuracy and reliability, providing valuable insights to quality managers, compliance officers, R&D engineers, and procurement professionals.
| Residue Class | Common Pesticides Detected |
|---|---|
| Organophosphates | Diazinon, Malathion, Parathion |
| Pyrethrins | Piperonyl butoxide, Pyrethroids |
| Aryloxyphenoxyacetic acids (AOAAs) | 2,4-Dichlorophenyl, 2,4-Dichloro-6-fluorobenzoic acid |
The benefits of our GC-MS service extend beyond mere detection; it helps in maintaining compliance with regulatory standards and enhancing product quality. By identifying pesticide residues early, stakeholders can take corrective actions to protect both public health and the environment.
