Estándares fisicoquímicos
Los estándares fisicoquímicos son materiales de referencia esenciales utilizados para garantizar la precisión y fiabilidad de diversas mediciones analíticas en la investigación científica y aplicaciones industriales. Esta categoría incluye una amplia gama de estándares como los estándares de conductividad, los estándares de electroquímica y los estándares y reactivos de ICP-OES/ICP-MS, que son cruciales para análisis elementales precisos y mediciones de conductividad. Las soluciones tampón de pH y los reactivos de carbono orgánico/inorgánico total son vitales para mantener los niveles de pH y medir el contenido de carbono en las muestras. Los estándares de la Farmacopea Europea (EP), la Farmacopea de los Estados Unidos (USP) y otras farmacopeas proporcionan puntos de referencia para el control de calidad farmacéutico. Otros estándares como los de turbidez, densidad, refractometría y viscosidad aseguran mediciones precisas de propiedades físicas. Los estándares especializados, como los de la industria del vino, lácteos y petroquímica, apoyan el control de calidad y el cumplimiento normativo en sectores específicos. Estos estándares fisicoquímicos desempeñan un papel crucial en garantizar la validez y reproducibilidad de los resultados experimentales, apoyando una amplia gama de aplicaciones, desde el monitoreo ambiental hasta las pruebas farmacéuticas y la ciencia de materiales.
