Certified reference materials CRM or reference materials RM are used in crop protection chemical residue analysis to validate analytical methods and evaluate the quality of measurement results. Imidacloprid is a common crop protection chemical used in tomato crops. A comprehensive study of the production storage transport and utilization of CRM imidacloprid in tomato matrix was conducted. After comparing the two frozen and freeze-dried production processes the freeze-dried production process was concluded to be superior. The CRM characterization process complies with ISO 17034 2016. The concentration of imidacloprid in tomato CRM is consistent with the maximum residue limit of imidacloprid according to the Codex and regulations of Circular 50 2016 TT-BYT of the Ministry of Health of Vietnam. At 4 C storage temperatures freeze-dried tomato CRM was predicted to be stable for at least 552 days while at -20 C the shelf life was at least 704 days. Keywords CRM RM tomatoes imidacloprid.
