The analysis for detection of contaminants, residual molecules, the suggested analysis of hygienic or product characterization are not exhaustive. They are a simplification of the analytical activities carried out in Chelab laboratories. The analytical methods are adjusted case by case according to the Customer needs and to the expected results with the aim to reach the best results.
