Product Overview
This Specpure® iridium plasma standard solution delivers exceptional purity and accuracy for demanding spectroscopic applications. Formulated at 1000µg/ml concentration in a stable aqueous matrix, it serves as a reliable calibration reference for iridium analysis across ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS) systems. The Specpure® grade ensures ultra-low trace metal impurities (<10ppb for most contaminants), with each batch accompanied by a certificate of analysis for full traceability. The solution’s homogeneous composition minimizes matrix effects, while its extended shelf life (when stored properly) reduces frequent recalibration needs. Packaged in high-density polyethylene bottles to prevent leaching, this standard maintains integrity even in long-term storage. The precise 1000µg/ml concentration allows for easy serial dilution to create working standards, while the nitric acid-based solvent system ensures complete metal solubility. Whether used for environmental testing, geological analysis, or materials research, this iridium standard provides the consistency required for ISO 17025-compliant laboratories and critical research applications.
FAQs
1. What is the solvent composition of this iridium standard solution?
The solution uses a dilute nitric acid matrix (typically 2-5% HNO₃) to ensure complete iridium solubility and long-term stability while minimizing interference in plasma-based techniques.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the Specpure® grade’s ultra-low impurity profile makes it suitable for both techniques, though you may need to dilute further for ICP-MS to avoid detector saturation at the 1000µg/ml concentration.
3. How does the Specpure® grade differ from standard reagent grades?
Specpure® standards undergo additional purification steps to achieve <10ppb levels for most trace metal contaminants, with certified values for major interferents like platinum group metals that are critical for iridium analysis.
4. What’s the recommended storage condition to maintain stability?
Store unopened at 15-25°C in the original bottle, away from direct sunlight. Once opened, tighten the cap immediately after use and avoid prolonged exposure to air to prevent concentration changes.
5. Is this solution compatible with organic solvents for specialized applications?
No, this aqueous standard isn’t designed for organic solvent compatibility. For organometallic applications, you would need to prepare derivatives separately or use specialized organic-soluble standards.
