ISO 22241 Gas Chromatographic Profiling of Pesticide Residues
The ISO 22241 standard specifies a methodology for the determination of pesticide residues in food and feed samples using gas chromatography coupled with mass spectrometry (GC-MS). This service is essential for ensuring compliance with regulatory limits set by various international standards such as EU legislation, FDA guidelines, and Codex Alimentarius recommendations.
Our laboratory utilizes state-of-the-art GC-MS systems that allow us to detect even trace amounts of pesticides. The process begins with the collection and preparation of samples, which involves thorough extraction techniques to ensure all residues are captured. Once extracted, the sample is injected into the GC system for separation based on chemical composition.
The method employed ensures high sensitivity and selectivity, making it suitable for both routine testing and complex matrix analysis. This approach provides reliable data that can be used for quality assurance purposes as well as research and development activities aimed at improving product safety and efficacy.
Our team of experts uses this technique to help clients meet stringent regulatory requirements around the world. By providing precise results, we enable businesses to maintain their competitive edge while adhering strictly to legal standards.
Applied Standards
| Standard | Description |
|---|---|
| ISO 22241:2019 | Method for the Determination of Pesticide Residues in Food and Feed by Gas Chromatography Coupled with Mass Spectrometry (GC-MS) |

Scope and Methodology
The methodology outlined in ISO 22241 involves several steps from sample preparation to final analysis. Initially, the samples are prepared according to specific protocols designed to extract pesticide residues effectively. This includes mechanical disruption of plant material or other relevant matrices followed by solvent-based extraction methods.
Following extraction, the solutions are cleaned up and concentrated if necessary before injection into the GC instrument. Separation occurs based on molecular structure and polarity, allowing for efficient identification of individual components within complex mixtures. The mass spectrometer then provides detailed information about each detected compound through its fragmentation patterns.
For accurate quantification, calibration curves are generated using known concentrations of standards. These help in determining exact amounts present in the samples under test. Our skilled analysts interpret these results to produce comprehensive reports that meet all relevant regulatory requirements.
Industry Applications
- Routine quality control checks for compliance with international standards.
- Potential identification of new pesticide residues not previously detected.
- Supporting research projects focused on reducing environmental impact by identifying more effective formulations.
