Product Overview
This Erbium plasma standard solution (10,000µg/ml) is formulated using Specpure® grade erbium, ensuring exceptional purity and consistency for demanding analytical applications. The solution is stabilized in a high-purity acid matrix to prevent precipitation and maintain long-term stability, making it ideal for use in inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectroscopy (AAS). The precise 10,000µg/ml concentration allows for easy dilution to prepare working standards across a wide analytical range without compromising accuracy. Each batch undergoes rigorous quality control testing to guarantee traceability and reliability in quantitative analysis. The solution is packaged in high-density polyethylene (HDPE) bottles to minimize contamination risks during storage and handling. Its low background interference profile makes it particularly suitable for trace metal analysis in complex matrices where sensitivity is critical. The Specpure® certification ensures compliance with international standards for reference materials, providing confidence in analytical results for research and industrial applications alike.
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 room temperature (15-25°C) in its original packaging. Once opened, we recommend using within 6 months for optimal performance.
2. Is this solution compatible with organic solvents for sample preparation?
This aqueous solution is primarily designed for direct use or dilution with deionized water. For organic solvent compatibility, we recommend preparing working standards in the same solvent matrix as your samples to avoid precipitation or phase separation.
3. What alternatives are available if I need a different Erbium concentration?
We offer custom dilution services for this 10,000µg/ml stock solution. Alternatively, you may consider our 1,000µg/ml Erbium standard solution (product code available on request) for applications requiring lower concentrations.
4. How should I handle and store this solution to maintain its integrity?
Store the unopened bottle upright at room temperature away from direct sunlight. After opening, tightly recap the bottle and store in a dedicated standards cabinet. Use clean, contamination-free pipettes and avoid repeated freeze-thaw cycles which may affect the solution’s homogeneity.
5. What documentation is provided with this standard solution?
Each bottle comes with a certificate of analysis (CoA) detailing the exact concentration, traceability to NIST standards, batch-specific purity data, and recommended storage conditions. The CoA also includes the expiration date and lot number for quality assurance purposes.
