Product Overview
This 10 ppm Ruthenium single-element standard is meticulously prepared in a 2% nitric acid matrix to ensure long-term stability and minimal matrix interference, making it ideal for high-sensitivity trace metal analysis. The standard undergoes rigorous multi-point calibration using NIST-traceable reference materials, guaranteeing ±1% accuracy with batch-specific certification. Its ultra-low particulate formulation (≤0.2 µm filtered) eliminates clogging risks in ICP-MS nebulizers, while the acidified matrix prevents precipitation or adsorption losses during storage. The solution is packaged in HDPE bottles with tamper-evident seals to maintain integrity during transit and lab handling. Compatibility is verified across Agilent, PerkinElmer, and Thermo Scientific ICP systems, with documented stability for 24+ months when stored at 15–25°C. Each batch includes a comprehensive Certificate of Analysis (CoA) detailing elemental purity (99.999% Ru), interferent screening (≤0.1 ppm total impurities), and method validation data for direct use in calibration curves or spike recovery tests without further dilution.
FAQs
1. What is the shelf life of this 10 ppm Ruthenium ICP standard?
The standard remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C in its original container. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used for ICP-MS analysis without further dilution?
Yes, the 10 ppm concentration is optimized for direct use in most ICP-MS calibration ranges (0.1–100 ppb). For ultra-trace analysis, serial dilution with 2% HNO₃ is recommended to minimize matrix effects.
3. Is this standard compatible with organic solvents for sample preparation?
The nitric acid matrix is miscible with most organic solvents like methanol or acetone at ratios up to 1:1, but compatibility should be verified for your specific application to prevent precipitation.
4. How is the concentration of 10 ppm verified?
Concentration is validated via gravimetric preparation using 99.999% pure Ruthenium metal, followed by ICP-OES cross-verification against NIST SRM 3134. The CoA includes uncertainty budgets and interferent screens.
5. What alternatives are available if I need a different concentration?
Custom concentrations (1 ppm, 100 ppm, or 1000 ppm) can be prepared on request with the same matrix and certification standards. Lead times typically range from 7–10 business days.
