Product Overview
This Specpure® europium plasma standard solution delivers unmatched precision with a certified 1000µg/ml concentration, engineered for demanding spectroscopic applications. The ultra-high-purity formulation minimizes matrix effects, ensuring reliable calibration curves in ICP-OES and AAS workflows. Each batch undergoes rigorous multi-element analysis to guarantee consistency, with traceability to NIST reference materials. The aqueous solution remains stable for extended periods when stored properly, eliminating the need for frequent recalibration. Its low acidity (typically <2% HNO₃) protects instrumentation while maintaining elemental integrity. The solution is pre-filtered to 0.2µm, preventing particulate interference in plasma-based techniques. Packaged in HDPE bottles with tamper-evident seals, it resists contamination during storage and handling. The Specpure® grade exceeds ACS and reagent-grade specifications, making it ideal for research requiring ultra-low detection limits. Compatible with most autosamplers, this standard eliminates the variability associated with in-house preparations. The europium concentration is verified via primary standardization methods, with uncertainty values provided for metrological traceability. This solution represents the gold standard for europium quantification in complex matrices, from environmental samples to advanced materials research.
FAQs
1. What is the shelf life of this europium plasma standard solution?
The solution maintains its certified concentration for 24 months from the date of manufacture when stored unopened at 15-25°C. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for ICP-MS applications?
While primarily designed for ICP-OES and AAS, the solution is compatible with ICP-MS when properly diluted. The Specpure® grade ensures minimal polyatomic interferences that could affect mass spectrometry results.
3. What dilution factors are recommended for calibration curves?
For typical calibration ranges, we recommend serial dilutions from 1:10 to 1:1000 using 2% HNO₃ as the diluent. The exact factors depend on your instrument’s sensitivity and expected sample concentrations.
4. How does the Specpure® grade differ from standard reagent grades?
Specpure® standards undergo additional purification steps to remove trace contaminants that could interfere with spectroscopic measurements. The certification process includes more rigorous testing for elemental impurities and stability.
5. What safety precautions should be taken when handling this solution?
Always wear nitrile gloves, safety goggles, and work in a fume hood. The solution contains nitric acid; neutralize spills with sodium bicarbonate and rinse with water. Avoid contact with skin and eyes.
