Thiram Residue Testing in Crops
The use of fungicides like Thiram is widespread in agricultural practices to control fungal diseases and enhance crop yield. However, the presence of residues from these chemicals can pose significant risks if not managed properly. Regulatory bodies worldwide have established maximum residue limits (MRLs) for various crops to ensure food safety and protect human health.
Our specialized Thiram residue testing service ensures that farmers, processors, and manufacturers adhere to stringent regulatory standards. This involves a comprehensive approach from sample collection to final analysis, ensuring accurate results tailored to your specific crop needs.
The process begins with the selection of representative samples which are then prepared according to standardized procedures outlined in international guidelines such as ISO 18567:2015 and ASTM E1403-19. Once prepared, these samples undergo extraction using solvents followed by purification steps ensuring minimal interference from other components.
For accurate quantification, advanced instrumentation like Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) is employed. These techniques provide high sensitivity and specificity allowing precise determination of Thiram levels down to parts per billion (ppb).
Our team of experts uses state-of-the-art equipment calibrated regularly against certified reference materials ensuring reliability and reproducibility of results. Compliance with international standards guarantees that you receive reliable data which can be used confidently when making decisions about crop quality control.
The service also includes detailed reporting including raw data, calculated concentrations along with any relevant metadata such as harvest date or location. This information is crucial for tracking trends over time and identifying potential issues early on in the production cycle.
