Product Description
When precision matters in your lab, the Rubidium 1000 ppm single-element standard solution delivers unmatched accuracy for ICP-based analyses. This high-purity solution, stabilized in nitric acid (HNO3), is specifically formulated for calibration curves, method development, and trace element quantification in environmental, geological, and industrial samples.
Rubidium, though less commonly analyzed than other alkali metals, plays a critical role in specialized research, including isotope studies, nuclear applications, and high-tech material synthesis. This standard solution ensures consistent performance across ICP-OES, ICP-MS, and other spectroscopic techniques, eliminating matrix interference risks that plague multi-element standards.
Whether you’re a student validating experimental protocols or a researcher fine-tuning analytical methods, this 100 ml pack provides ample volume for repeated calibrations without compromising stability. The HNO3 matrix guarantees long-term shelf life while maintaining traceability to NIST standards—a must for publishable results.

Why This Rubidium Standard Stands Out
Unlike generic multi-element mixes, this dedicated rubidium standard offers several advantages for discerning analysts:
First, the 1000 ppm concentration strikes the perfect balance between sensitivity and dilution flexibility. You can easily prepare working standards from 0.1 ppm to 100 ppm without sacrificing precision. The nitric acid matrix, maintained at optimal pH, prevents precipitation and ensures homogeneous distribution during aspiration.
Second, the solution undergoes rigorous quality control, including ICP-OES verification against certified reference materials. Each batch comes with a certificate of analysis detailing rubidium content, potential impurities, and expiration data—critical for GLP-compliant laboratories.
Finally, the 100 ml packaging reduces waste while providing sufficient volume for routine lab operations. The amber glass bottle with tamper-evident seal protects against light-induced degradation, a common issue with alkali metal standards.
Applications in Real-World Research
This rubidium standard solution finds applications across diverse scientific disciplines:
In geochemistry, researchers use it to quantify rubidium in mineral samples, helping reconstruct geological timelines through Rb-Sr dating methods. Environmental scientists rely on it to monitor rubidium contamination in water sources near electronic waste processing sites.
Material scientists calibrate their instruments to detect rubidium traces in superconductors and photovoltaic materials, where even ppm-level impurities can alter performance. Forensic labs occasionally employ rubidium analysis to differentiate glass samples in criminal investigations.

Handling and Storage Guidelines
While this solution is stabilized for long-term use, proper handling ensures consistent performance:
Store the unopened bottle at 15-25°C in its original packaging, away from direct sunlight. Once opened, use within 6 months for optimal accuracy. Always use acid-washed volumetric glassware when preparing dilutions to prevent contamination.
For disposal, neutralize small quantities with sodium bicarbonate before discarding according to local hazardous waste regulations. Never pour concentrated standards down laboratory drains.
Compatibility with Common Instruments
This rubidium standard integrates seamlessly with major ICP systems:
PerkinElmer Optima series, Agilent 5100/5110 ICP-OES, Thermo Scientific iCAP series, and Shimadzu ICPE-9800 all demonstrate excellent linearity when calibrated with this solution. For ICP-MS users, the low matrix interference makes it ideal for quadrupole and high-resolution instruments alike.

FAQs
Frequently Asked Questions
What’s the shelf life of this rubidium standard solution?
When stored unopened at room temperature, the solution maintains its certified concentration for 24 months from the manufacture date. After opening, we recommend using it within 6 months for optimal accuracy.
Can I use this for both ICP-OES and ICP-MS?
Absolutely. The solution is formulated to work with both techniques. For ICP-MS, you may need to dilute further depending on your instrument’s sensitivity and the expected rubidium concentrations in your samples.
How do I prepare a 10 ppm working standard?
Simply pipette 1 ml of this 1000 ppm solution into a 100 ml volumetric flask and dilute to volume with 2% HNO3. This gives you a stable 10 ppm rubidium standard ready for calibration.
Is this solution traceable to NIST standards?
Yes, each batch is prepared using rubidium nitrate of certified purity and verified against NIST-traceable reference materials. The certificate of analysis included with your order provides full traceability documentation.
What safety precautions should I take when handling this solution?
While the rubidium concentration is low, the nitric acid matrix requires standard acid handling precautions. Always wear nitrile gloves, safety goggles, and work in a fume hood when preparing dilutions or handling the concentrated solution.
