Product Overview
The Specpure® Strontium standard solution delivers unmatched precision for plasma spectroscopy applications, formulated with 100µg/ml natural strontium in a stabilized aqueous matrix. Engineered under stringent quality controls, this solution adheres to Specpure®’s ultra-high purity standards, ensuring minimal interference from trace contaminants that could skew analytical results. The solution’s homogeneous composition guarantees consistent performance across multiple calibration cycles, eliminating batch-to-batch variability. Its long-term stability—validated through accelerated aging tests—prevents degradation or precipitation, even under fluctuating storage conditions. The 50ml pack size balances cost-efficiency with practical lab usage, reducing waste while providing sufficient volume for routine standardization. Compatibility with most plasma instruments (ICP-OES, ICP-MS, AAS) is verified, with no matrix effects observed in multi-element analyses. Each batch undergoes rigorous certification, with a certificate of analysis provided for traceability. The solution’s low acidity (typically <2% HNO₃) preserves instrument longevity while maintaining elemental solubility. For labs requiring NIST-traceable references, this standard aligns with international metrological protocols, offering confidence in quantitative accuracy. The amber glass packaging with PTFE-lined cap prevents leaching or evaporation, further safeguarding integrity during storage or transport.
FAQs
1. What is the shelf life of this Specpure® Strontium 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 stability may extend if handled under inert conditions.
2. Can this standard be used for both ICP-OES and ICP-MS without dilution?
Yes, the 100µg/ml concentration is suitable for direct use in most ICP-OES applications. For ICP-MS, dilution may be required depending on the instrument’s linear range and the desired detection limits for strontium isotopes.
3. Are there any known interferences with other elements in multi-element analysis?
Specpure® Strontium is designed to minimize spectral overlaps. However, high concentrations of calcium or barium may require mathematical correction or alternative wavelengths (e.g., Sr 407.771 nm) to avoid interference.
4. How should I dispose of unused or expired solution?
Neutralize with a compatible base (e.g., sodium hydroxide) to pH 6–8 before disposal as hazardous chemical waste, following local environmental regulations. Never dispose of untreated solution in drains.
5. Is this standard compatible with organic solvents for specific applications?
The aqueous matrix is optimized for plasma spectroscopy. For organic-soluble requirements, consider alternative Specpure® standards in acidic or solvent-based formulations, as this solution may precipitate or react with non-polar solvents.
