CAS 7440-52-0: Solution standard d'absorption atomique d'erbium
Description :
Solution standard d'absorption atomique d'erbium est une préparation utilisée principalement en chimie analytique pour la détermination de la concentration d'erbium dans divers échantillons par spectroscopie d'absorption atomique (AAS). L'erbium, avec le symbole chimique Er et le numéro CAS 7440-52-0, est un élément lanthanide connu pour son apparence métallique argentée et fait partie des éléments des terres rares. Sous forme de solution, l'erbium existe généralement sous forme d'ions d'erbium, souvent dans l'état d'oxydation +3, qui est la forme la plus stable et courante dans les solutions aqueuses. La solution standard est caractérisée par sa concentration spécifique, qui est cruciale pour la calibration dans l'analyse spectroscopique. Les ions d'erbium présentent des longueurs d'onde d'absorption distinctes, permettant une quantification précise dans diverses matrices, y compris des échantillons environnementaux et des applications en science des matériaux. La solution doit être manipulée avec soin, en respectant les protocoles de sécurité, car elle peut contenir des acides ou d'autres réactifs pouvant être dangereux. Des conditions de stockage appropriées sont essentielles pour maintenir l'intégrité de la solution et prévenir la dégradation ou la contamination.

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.Formule :ErDegré de pureté :Min. 95%Masse moléculaire :167.26 g/molErbium foil, 0.025mm (0.001 in.) thick, 99.9% (REO)
CAS :Erbium foil used in Physical Vapor Deposition (PVD) processes, including thermal and electron-beam (e-beam) evaporation, for the preparation of thin films.
