CAS 7440-52-0: Solución estándar de absorción atómica de erbio

Descripción:
Solución estándar de absorción atómica de erbio es una preparación utilizada principalmente en química analítica para la determinación de la concentración de erbio en diversas muestras a través de la espectroscopia de absorción atómica (AAS). El erbio, con el símbolo químico Er y el número CAS 7440-52-0, es un elemento lantánido conocido por su apariencia metálica blanco plateada y forma parte de los elementos de tierras raras. En forma de solución, el erbio típicamente existe como iones de erbio, a menudo en el estado de oxidación +3, que es la forma más estable y común en soluciones acuosas. La solución estándar se caracteriza por su concentración específica, que es crucial para la calibración en análisis espectroscópicos. Los iones de erbio exhiben longitudes de onda de absorción distintas, lo que permite una cuantificación precisa en diversas matrices, incluyendo muestras ambientales y aplicaciones en ciencia de materiales. La solución debe manejarse con cuidado, adhiriéndose a los protocolos de seguridad, ya que puede contener ácidos u otros reactivos que pueden ser peligrosos. Las condiciones de almacenamiento adecuadas son esenciales para mantener la integridad de la solución y prevenir la degradación o contaminación.

  • Erbium

    CAS:
    Erbium is a chemical element with atomic number 68. Erbium lasers are used to ablate tissue and as a light source for medical imaging. The laser light signal is generated by the decay of erbium-doped yttrium aluminum garnet (Er:YAG) rods, which emit infrared light at 2.94 μm wavelength. Er:YAG lasers have been used in the treatment of congestive heart failure and primary breast cancers. They have also been used to collect blood samples for analysis, as well as to measure intramolecular hydrogen bonds in proteins and DNA. Erbium has also been shown to inhibit mitochondrial membrane potential and oxidative injury, which may lead to apoptosis pathway activation and cell death.
