Étalons physico-chimiques
Les standards physicochimiques sont des matériaux de référence essentiels utilisés pour garantir la précision et la fiabilité de diverses mesures analytiques dans la recherche scientifique et les applications industrielles. Cette catégorie comprend une large gamme de standards tels que les standards de conductivité, les standards d'électrochimie et les standards et réactifs ICP-OES/ICP-MS, qui sont cruciaux pour les analyses élémentaires précises et les mesures de conductivité. Les solutions tampons de pH et les réactifs de carbone organique/inorganique total sont vitaux pour maintenir les niveaux de pH et mesurer la teneur en carbone dans les échantillons. Les standards de la Pharmacopée Européenne (EP), de la Pharmacopée des États-Unis (USP) et d'autres pharmacopées fournissent des points de référence pour le contrôle de qualité pharmaceutique. D'autres standards, tels que ceux de turbidité, de densité, de réfractométrie et de viscosité, garantissent des mesures précises des propriétés physiques. Les standards spécialisés, comme ceux pour l'industrie du vin, des produits laitiers et pétrochimiques, soutiennent le contrôle de qualité et la conformité réglementaire dans des secteurs spécifiques. Ces standards physicochimiques jouent un rôle crucial dans l'assurance de la validité et de la reproductibilité des résultats expérimentaux, soutenant une large gamme d'applications, de la surveillance environnementale aux tests pharmaceutiques et à la science des matériaux.
