bakery products, fruit and vegetable sauces. Liquid matrices were
soft drinks, alcoholic aperitifs, clear fruit juices. The evaluated parameters
were the following: linearity of response, applicability
range, accuracy as trueness and precision, limit of detection (LOD),
limit of quantification (LOQ). All parameters were assessed for both
