CAS 7440-52-0: Solução padrão de absorção atômica de érbio
Descrição:
Solução padrão de absorção atômica de érbio é uma preparação utilizada principalmente em química analítica para a determinação da concentração de érbio em várias amostras através da espectroscopia de absorção atômica (AAS). O érbio, com o símbolo químico Er e número CAS 7440-52-0, é um elemento lantânido conhecido por sua aparência metálica prateada e faz parte dos elementos de terras raras. Em forma de solução, o érbio geralmente existe como íons de érbio, muitas vezes no estado de oxidação +3, que é a forma mais estável e comum em soluções aquosas. A solução padrão é caracterizada por sua concentração específica, que é crucial para a calibração na análise espectroscópica. Os íons de érbio exibem comprimentos de onda de absorção distintos, permitindo uma quantificação precisa em várias matrizes, incluindo amostras ambientais e aplicações em ciência dos materiais. A solução deve ser manuseada com cuidado, aderindo aos protocolos de segurança, pois pode conter ácidos ou outros reagentes que podem ser perigosos. Condições de armazenamento adequadas são essenciais para manter a integridade da solução e prevenir degradação ou contaminação.

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.Fórmula:ErPureza:Min. 95%Peso molecular:167.26 g/molRef: 3D-FE159513
