Product Overview
This Erbium AAS standard solution from Specpure® delivers exceptional purity and consistency for demanding analytical applications. Formulated at a precise concentration of 1000µg/ml, it serves as a reliable reference material for atomic absorption spectroscopy (AAS) and other trace element analysis techniques. The solution is prepared using ultra-high purity Erbium (Er) in a stabilized matrix, ensuring long-term stability and minimal interference in spectroscopic measurements. Each batch undergoes rigorous quality control to meet international standards, making it ideal for laboratories requiring reproducible results. The Specpure® grade guarantees low levels of contaminants, while the liquid form allows for easy dilution and handling. Whether used for calibration curves, method validation, or routine analysis, this standard solution provides the accuracy needed for critical measurements. The solution is packaged in high-density polyethylene bottles to prevent contamination and maintain integrity during storage.
FAQs
1. What is the shelf life of this Erbium AAS standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for ICP-OES or ICP-MS applications?
While primarily designed for AAS, the high purity of this Specpure® solution makes it compatible with ICP-OES and ICP-MS after appropriate dilution and matrix matching.
3. What diluent is recommended for preparing lower concentration standards?
Use 2% nitric acid (HNO₃) prepared with ultrapure water (18.2 MΩ·cm) as the diluent to maintain stability and prevent precipitation.
4. How should this solution be stored to maintain accuracy?
Store the unopened bottle at 15-25°C in a clean, dry environment away from direct sunlight. Tightly recap after each use to minimize contamination.
5. Is this solution traceable to NIST or other international standards?
The Erbium concentration is certified against primary standards traceable to NIST SRMs, ensuring metrological reliability for your analyses.
