dans la nature : Par exemple, lorsque la lumi\u00e8re traverse l&#8217;eau, le faisceau lumineux est r\u00e9fl\u00e9chi &#8211; et les objets sous l&#8217;eau semblent avoir des proportions diff\u00e9rentes de celles observ\u00e9es au-dessus de l&#8217;eau. Ce ph\u00e9nom\u00e8ne est appel\u00e9 r\u00e9flexion et r\u00e9fraction.<\/p>\n<p>La r\u00e9fraction et la r\u00e9flexion de la lumi\u00e8re se produisent lorsque la lumi\u00e8re frappe l&#8217;interface d&#8217;un milieu ayant des indices de r\u00e9fraction diff\u00e9rents. Par cons\u00e9quent, la r\u00e9fractom\u00e9trie est g\u00e9n\u00e9ralement la mesure de l&#8217;indice de r\u00e9fraction et son interpr\u00e9tation dans diff\u00e9rentes conditions initiales. Les mesures r\u00e9fractom\u00e9triques peuvent \u00eatre effectu\u00e9es en laboratoire ou en ligne, c&#8217;est-\u00e0-dire pendant un processus de production de substances liquides de toute nature.<\/p>\n<p>L&#8217;examen et le contr\u00f4le de la qualit\u00e9 des huiles, des graisses, du sucre et des substances contenant du sucre sont les principaux domaines traditionnels de la mesure de la r\u00e9fraction. En outre, la limonade, la bi\u00e8re et les boissons alcoolis\u00e9es appartiennent \u00e0 la classe des mat\u00e9riaux qui sont g\u00e9n\u00e9ralement analys\u00e9s par un capteur.<\/p>\n<p>La plupart des \u00e9chantillons liquides et solides translucides sont mesur\u00e9s par r\u00e9fractom\u00e9trie.

Il est \u00e9galement possible que diff\u00e9rents mat\u00e9riaux aient le m\u00eame indice de r\u00e9fraction \u00e0 diff\u00e9rentes concentrations. Ainsi, une d\u00e9termination claire des substances liquides ne peut \u00eatre r\u00e9ussie qu&#8217;avec des m\u00e9langes binaires (m\u00e9langes constitu\u00e9s de deux compos\u00e9s).<\/p>\n<p>Dans la pratique, l&#8217;indice de r\u00e9fraction d\u00e9termine le rapport de m\u00e9lange de mani\u00e8re assez pr\u00e9cise et simple, m\u00eame pour les solutions \u00e0 plusieurs composants, car il suffit g\u00e9n\u00e9ralement de d\u00e9terminer la concentration de l&#8217;un des composants. Il s&#8217;agit donc d&#8217;une mesure quantitative. Pour les compos\u00e9s connus, la qualit\u00e9 peut \u00e9galement \u00eatre d\u00e9termin\u00e9e. Pour des produits comme l&#8217;huile d&#8217;olive ou le jus d&#8217;orange, la valeur mesur\u00e9e dans une certaine fourchette correspond \u00e0 une certaine qualit\u00e9.<\/p>\n<p>Il existe une corr\u00e9lation certaine entre l&#8217;indice de r\u00e9fraction et la composition de nombreuses solutions \u00e0 deux compos\u00e9s. L&#8217;exemple le plus connu d&#8217;un tel m\u00e9lange est une solution de saccharose dans l&#8217;eau, qui a \u00e9t\u00e9 \u00e9tudi\u00e9e de mani\u00e8re approfondie. L&#8217;indice de r\u00e9fraction d&#8217;un r\u00e9fractom\u00e8tre peut \u00eatre mis \u00e0 l&#8217;\u00e9chelle de sorte que la valeur indique directement la substance s\u00e8che en % RTS. Pour le saccharose, cette unit\u00e9 est \u00e9galement appel\u00e9e Brix (abr\u00e9viation Brix).<\/p>\n<p>La densit\u00e9 des \u00e9chantillons peut \u00e9galement \u00eatre d\u00e9termin\u00e9e par r\u00e9fractom\u00e9trie. En r\u00e8gle g\u00e9n\u00e9rale, la densit\u00e9 et la mati\u00e8re s\u00e8che correspondent l&#8217;une \u00e0 l&#8217;autre dans les mesures optiques.<\/p>\n<p>Les r\u00e9fractom\u00e8tres convertissent les indices de r\u00e9fraction mesur\u00e9s en concentration ou en densit\u00e9.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element
