The services at CAL are used regularly by the legal profession. The analysis of products relating to personal injury cases or simple consumer complaints use methods such as HPLC or GC-MS. Other procedures employed are Enzyme-linked Immunosorbant Assays (ELISA) e.g. assays for allergens such as gluten, peanut and sesame seed. CAL provides a wide range of analysis for legal purposes and will attend court to act as expert witness in many cases. Where necessary, CAL can arrange for toxicology opinions and reports by expert toxicologists who may be required to interpret the data obtained by chemical analysis.
