Product Overview
This Specpure® Rubidium plasma standard solution delivers 1000µg/ml concentration in a matrix optimized for plasma spectrometry applications. Manufactured under stringent ISO-guided protocols, it guarantees minimal interference from metallic impurities, ensuring reliable calibration curves and quantitative accuracy in trace element analysis. The solution is stabilized with high-purity acids to prevent precipitation and maintain homogeneity over extended storage periods. Each batch undergoes multi-point certification against NIST-traceable reference materials, with certificates of analysis provided for lot-specific purity verification. The aqueous formulation eliminates residue formation in nebulizers, reducing instrument maintenance downtime. Compatible with most ICP-OES and AAS systems, this standard solution eliminates the need for in-house dilution preparation, saving lab time while maintaining analytical precision. The amber glass packaging with PTFE-lined caps prevents contamination from leachables, preserving the solution’s integrity until the last drop. Ideal for laboratories requiring consistent performance in environmental testing, geological analysis, or materials characterization where rubidium quantification is critical.
FAQs
1. What is the shelf life of this rubidium standard solution when unopened?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C in its original packaging. Always check the expiration date on the label before use.
2. Can this standard be used directly for ICP-MS analysis?
While optimized for ICP-OES and AAS, this 1000µg/ml concentration may require dilution for ICP-MS applications to avoid detector saturation. Typical working ranges for ICP-MS are 1-100µg/L.
3. What acid matrix is used in this rubidium standard?
The solution uses a nitric acid matrix (2-5% v/v) to ensure complete dissolution and stability of rubidium ions without introducing spectral interferences.
4. How should I handle potential contamination during aliquoting?
Use dedicated polypropylene or PTFE pipette tips and work in a laminar flow hood if available. Always wear nitrile gloves and avoid touching the bottle’s inner neck or cap liner.
5. Is this standard compatible with organic solvent-based sample preparation?
This aqueous standard isn’t designed for direct mixing with organic solvents. For organic matrices, consider evaporating an aliquot and reconstituting in your solvent system, or use a dedicated organometallic standard.
