Notes d'Application Agro-Allimentaire

La nature très complexe des matrices rencontrées dans les produits agro-alimentaires nécessite souvent la réalisation d'étapes de préparation des échantillons avant de pouvoir procéder à l’analyse des composés d'intérêt. L'automatisation de cette étape de préparation de l'échantillon permet d’augmenter la productivité du laboratoire, d'améliorer la fiabilité et la répétabilité des résultats tout en réduisant le risque d'erreurs.
