Pesticide Testing & Agrochemical Residue Analysis

ALS has been performing pesticide residue analysis for over 30 years and recognises the need for fast, accurate and reliable analysis. In a world where food demand is ever increasing, the use and control of agrochemicals are closely monitored. Keeping on top of ever changing maximum residue levels (MRL's) is no easy task but having an experienced and knowledgeable laboratory team at your service definitely helps.

Our team have knowledge and experience of not only the analysis of individual or groups of pesticides but also targeted pesticide testing specific to certain foods or crops. We offer technical support to assist in devising tailor-made pesticide residue schedules or protocols by utilising our technical expertise and knowledge of historic residue patterns or pesticide usage.
