Product Overview
This mercury plasma standard solution delivers a certified concentration of 10,000µg/ml (1% w/v) in a Specpure® grade matrix, ensuring exceptional purity and stability for demanding analytical applications. The solution is prepared using ultra-high-purity mercury (Hg) dissolved in a nitric acid matrix, minimizing matrix interferences for accurate calibration curves in spectroscopic techniques. The Specpure® certification guarantees traceability to NIST standards, with rigorous quality control to eliminate contaminants that could affect sensitivity. The solution is packaged in HDPE bottles to prevent leaching or adsorption, maintaining integrity during storage. Its high concentration allows for precise dilution to create working standards, reducing preparation time while maintaining accuracy. The low background interference makes it particularly suitable for environmental, pharmaceutical, and industrial testing where mercury detection limits are critical. Each batch undergoes multi-point verification to ensure consistency across lots, with stability guaranteed for 24 months when stored under recommended conditions.
FAQs
1. What is the matrix composition of this mercury standard solution?
The solution uses a dilute nitric acid matrix (typically 2-5% v/v) to stabilize the mercury while minimizing spectral interferences during analysis. The exact composition is optimized for compatibility with most ICP-OES and AAS instruments without requiring additional matrix matching.
2. Can this standard be used directly for ICP-MS analysis?
While the solution is compatible with ICP-MS, the high concentration (10,000µg/ml) requires significant dilution—typically 1:1000 or more—to fall within the instrument’s linear range. The Specpure® grade ensures minimal polyatomic interferences, but we recommend verifying compatibility with your specific ICP-MS method.
3. What alternatives exist for lower concentration mercury standards?
For applications requiring ready-to-use standards, consider our 1,000µg/ml or 100µg/ml mercury solutions in the same Specpure® grade. These eliminate dilution steps while maintaining traceability. Alternatively, our mercury single-element standards in 2% HNO₃ offer similar purity for custom preparations.
4. How should this solution be stored to maintain stability?
Store the unopened bottle at 15–25°C in its original packaging, away from direct sunlight and sources of heat. Once opened, tightly recap after each use and store upright to prevent leaks. Avoid freezing, as this may alter the matrix composition or cause container stress.
5. Is this standard traceable to international reference materials?
Yes, the Specpure® certification includes traceability to NIST SRM 3133 (mercury standard) and is accompanied by a certificate of analysis detailing the reference materials used for calibration. The uncertainty values provided account for homogeneity, stability, and characterization measurements.
