Product Overview
This Erbium plasma standard solution (1000µg/ml) is formulated with Specpure® grade purity, ensuring ultra-low impurity levels for precise analytical applications. The solution is stabilized in a high-purity acid matrix (typically nitric acid) to prevent precipitation and maintain long-term homogeneity, making it ideal for instrument calibration and quality control in trace element analysis. Each batch undergoes rigorous testing for accuracy, with concentration values traceable to NIST or equivalent standards. The aqueous form eliminates particulate contamination risks, while the sealed packaging preserves integrity during storage. Compatible with most ICP-OES, ICP-MS, and AAS systems, this standard delivers consistent signal response across multiple runs. The 1000µg/ml concentration allows for easy dilution to working ranges without compromising linearity. Packaged in HDPE bottles with tamper-evident seals, the solution resists leaching and external contamination. For labs requiring high-throughput analysis, the larger 100ml pack size reduces frequent replenishment needs while maintaining the same stringent quality controls as the 50ml option.
FAQs
1. What is the shelf life of this Erbium plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C. Once opened, use within 6 months for optimal accuracy, though recertification via in-house standards may extend usability.
2. Can this standard be used for both ICP-OES and ICP-MS calibration?
Yes, the 1000µg/ml concentration is suitable for both techniques. For ICP-MS, further dilution (typically 1:100 or 1:1000) is recommended to match the instrument’s linear range, while ICP-OES may require less dilution depending on the emission line used.
3. What acid matrix is used in this solution, and is it compatible with my instrument?
The solution is stabilized in 2–5% high-purity nitric acid, which is compatible with most plasma-based instruments. For systems sensitive to acid content, a quick rinse with 1% HNO₃ between samples is advised to prevent carryover.
4. How does Specpure® grade differ from standard reagent-grade Erbium solutions?
Specpure® grade undergoes additional purification steps to remove metallic and anionic impurities (e.g., <10 ppb for most contaminants), ensuring minimal spectral interferences. Standard reagent grades may contain higher impurity levels, affecting calibration accuracy at trace concentrations.
5. Is this solution traceable to international standards?
Yes, the concentration is certified against NIST SRM or equivalent primary standards, with a certificate of analysis provided for each batch. The traceability chain is documented to ISO/IEC 17025 guidelines for analytical reliability.
