Balances pour réfractomètres

Échantillons et leur indice de réfraction (nD)

SCHMIDT + HAENSCH propose un certain nombre de réfractomètres différents qui peuvent être utilisés pour déterminer l’indice de réfraction et la concentration en liquide d’une variété d’échantillons. Afin de choisir le réfractomètre de processus ou le réfractomètre de laboratoire optimal pour votre application spécifique, il convient de déterminer l’échelle de votre échantillon et la température de mesure souhaitée. Cela vous permettra non seulement d’accroître la fiabilité de vos résultats de mesure, mais aussi de faire des économies en choisissant le réfractomètre qui vous convient. La programmation de plusieurs échelles dans un même réfractomètre est également possible.

Dans le tableau ci-dessous, les indices de réfraction d’une variété d’échantillons ont été déterminés avec précision, mesurés à 20°C et λ = 589 nm comme mesure de référence. Des températures différentes entraînent des indices de réfraction différents (nD). Si un échantillon manque dans le tableau ou si vous avez besoin d’une référence de température différente, n’hésitez pas à nous contacter pour toute question supplémentaire.

Nous proposons à nos clients le développement d’échelles, le conseil en applications et l’ingénierie de nouvelles applications. Notre équipe de vente se fera un plaisir de répondre à vos questions.
