Pesticide Ion Residue Testing
The testing of pesticide ion residues is an essential component in ensuring agricultural products meet stringent quality and regulatory standards. This service focuses on identifying and quantifying trace levels of ionic forms of pesticides that may remain in or on food items, crops, soil, water, and other environmental samples. The primary goal is to ensure compliance with international safety regulations such as ISO, ASTM, EN, IEC, and others.
Our laboratory uses advanced analytical techniques including Inductively Coupled Plasma Mass Spectrometry (ICP-MS), High Performance Liquid Chromatography coupled with Tandem Mass Spectrometry (HPLC/MS/MS), and Gas Chromatography-Mass Spectrometry (GC-MS). These methods allow for precise detection down to parts per billion levels, providing reliable data that is crucial for regulatory compliance.
Specimen preparation involves careful handling of samples to prevent contamination. This includes the use of appropriate solvents, filtration techniques, and derivatization processes where necessary. The type of sample will dictate specific procedures; for instance, soil might require extraction with acid or alkali solutions while water samples may need purification steps to remove interfering ions.
Our team follows strict protocols outlined by relevant international standards such as ISO 17025 and IEC 61964. These guidelines ensure that all tests are conducted under controlled conditions, reducing variability in results. The use of certified reference materials further enhances the accuracy and precision of our measurements.
Reporting is comprehensive, detailing not only detected residues but also providing interpretation based on thresholds set by regulatory bodies like WHO, FAO, and EPA. We provide detailed reports that include raw data along with calculated concentrations, comparison to standard limits, and recommendations for future actions if necessary.
The importance of pesticide ion residue testing cannot be overstated given the potential health risks associated with exposure to even trace amounts of certain pesticides. By offering this service, we help protect public health while supporting sustainable agricultural practices.
Scope and Methodology
The scope of our pesticide ion residue testing encompasses a wide range of ionic forms commonly found in agricultural chemicals. These include but are not limited to organophosphates, carbamates, pyrethroids, neonicotinoids, and sulfonylureas. Our methodology employs state-of-the-art instrumentation capable of detecting these compounds at extremely low concentrations.
- Organophosphate: Detected using HPLC/MS/MS with a lower limit of detection (LOD) of 0.1 ng/mL.
- Carbamate: Identified via GC-MS with an LOD of 0.2 ng/mL.
- Pyrethroid: Analyzed by ICP-MS achieving LOD down to 0.05 ng/mL.
To achieve accurate results, it is important that samples are prepared correctly before analysis. This includes thorough extraction processes tailored specifically for each type of sample (plant tissue, soil, water). Once extracted, solutions undergo dilution if necessary followed by introduction into the analytical instrument. Careful attention must be paid during this process to avoid introducing any contaminants which could affect results.
The acceptance criteria used in our laboratory are derived from internationally recognized standards such as ISO 18329 for pesticides in food and feed, and EPA Method 503.2 for determining pesticide residues in water by capillary gas chromatography.
