Product Overview
This Specpure® Europium plasma standard solution delivers 10,000µg/ml concentration in a stabilized nitric acid matrix, engineered for unmatched precision in plasma-based analytical techniques. The ultra-high purity grade ensures minimal interference from trace contaminants, making it ideal for calibration curves in ICP-OES, ICP-MS, and AAS applications. Each batch undergoes rigorous multi-element analysis to guarantee consistency, with certification documentation provided for full traceability. The solution’s long-term stability (minimum 24 months when stored properly) eliminates frequent recalibration needs, while the nitric acid base prevents precipitation or adsorption losses. Compatible with most autosamplers and nebulizers, this standard solution reduces matrix effects that commonly plague lower-grade alternatives. The Specpure® designation signifies adherence to the strictest manufacturing protocols, including sub-ppb impurity control for critical elements like Na, K, Ca, and Fe. For laboratories requiring NIST-traceable reference materials, this Europium standard offers a cost-effective alternative without compromising analytical integrity. The amber glass packaging with PTFE-lined caps ensures zero leaching or contamination during storage or transport.
FAQs
1. What is the shelf life of this Europium plasma standard solution?
The solution remains stable for at least 24 months from the date of manufacture when stored unopened at 15-25°C in its original container. Always check the certificate of analysis for batch-specific expiration.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 10,000µg/ml concentration is optimized for dilution across both techniques. For ICP-MS, we recommend further dilution to avoid detector saturation, typically working in the 1-100µg/L range.
3. What acid matrix is used, and does it require neutralization before disposal?
The solution uses 2-5% high-purity nitric acid as the matrix. While the acid concentration is relatively low, local environmental regulations may require neutralization with sodium hydroxide or soda ash before disposal.
4. How does this compare to NIST-traceable Europium standards?
This Specpure® standard is manufactured under ISO 17034 and ISO/IEC 17025 guidelines with full traceability to NIST SRMs, offering comparable accuracy at a more accessible price point for routine laboratory use.
5. What’s the recommended storage condition to prevent contamination?
Store upright in the original amber glass bottle at 15-25°C, away from direct sunlight and volatile organic compounds. Avoid repeated opening to minimize exposure to lab air contaminants.
