Product Overview
This Europium AAS standard solution from Specpure® delivers exceptional purity and consistency, formulated at a concentration of 1000µg/ml to meet the stringent demands of trace metal analysis. The solution is prepared using ultra-high-purity reagents and deionized water, ensuring minimal interference and maximum accuracy in atomic absorption spectroscopy (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), and mass spectrometry (ICP-MS). The Specpure® grade guarantees low background contamination, making it ideal for calibration curves, method validation, and routine laboratory testing where precision is critical. Housed in a high-density polyethylene (HDPE) bottle, the solution remains stable over extended periods, resisting leaching or degradation that could compromise results. Its homogeneous composition eliminates the need for additional dilution in most applications, streamlining workflow efficiency. Whether used as a primary standard or for quality control checks, this Europium solution adheres to international analytical standards, providing reliable performance for researchers and technicians. The 500ml pack size offers an optimal balance between cost-effectiveness and reduced handling frequency, minimizing the risk of contamination during repeated use.
FAQs
1. What is the shelf life of this Europium AAS standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature in its original container. Always check the label for the exact expiry date.
2. Can this solution be used directly for ICP-MS without further dilution?
While the 1000µg/ml concentration is suitable for many AAS applications, ICP-MS typically requires lower concentrations (ppb range). Dilution with ultra-pure water or matrix-matched solvents is recommended for ICP-MS use.
3. Is this Europium standard compatible with organic solvents for specific applications?
The solution is aqueous-based and not designed for direct solubility in organic solvents. For organic-phase applications, consider evaporating the solvent under controlled conditions and redissolving in the desired organic medium.
4. How should I store this solution to maintain its integrity?
Store the unopened bottle at 15–25°C in a clean, dry environment away from direct sunlight and sources of heat. Once opened, tightly recap the bottle after each use to prevent contamination or evaporation.
5. Are there lower-concentration alternatives available for this Europium standard?
Lower concentrations (e.g., 10µg/ml or 100µg/ml) can be prepared by serial dilution of this 1000µg/ml stock solution using high-purity diluents. Pre-diluted standards may also be sourced separately if required.
