Product Overview
The Rhodium 1000 ppm ICP-ML single-element standard delivers exceptional purity and consistency for demanding trace metal analysis applications. Formulated in a 2% nitric acid matrix, this aqueous solution ensures complete solubility and long-term stability, eliminating precipitation risks during storage or dilution. The standard is manufactured under ISO 17034 and ISO/IEC 17025 guidelines, with each batch accompanied by a comprehensive Certificate of Analysis documenting the exact concentration (1000 ± 20 ppm) and potential impurities. The low matrix interference profile makes it ideal for ICP-OES and ICP-MS instrumentation, where spectral overlaps can compromise data integrity. Packaged in HDPE bottles with tamper-evident seals, the solution maintains its certified concentration for 24 months when stored at 15-25°C. The nitric acid base not only stabilizes the rhodium ions but also matches the acidity requirements of most ICP sample preparation protocols, reducing the need for additional matrix matching. This standard is particularly valuable for laboratories requiring NIST-traceable calibration where rhodium serves as an internal standard or when analyzing platinum group metals in complex matrices.
FAQs
1. What is the exact matrix composition of this Rhodium standard?
The standard is prepared in 2% high-purity nitric acid (HNO₃) using Type I water, with residual acidity carefully controlled to prevent precipitation while maintaining compatibility with most ICP sample introduction systems.
2. Can this standard be used for ICP-OES and ICP-MS simultaneously?
Yes, the 1000 ppm concentration is suitable for both techniques, though you may need to dilute it further for ICP-MS applications where lower detection limits are required, typically in the ppb range.
3. What is the shelf life after opening the bottle?
Once opened, the standard remains stable for 12 months when stored properly at 15-25°C in its original container with the cap tightly sealed to prevent evaporation and contamination.
4. Are there any known spectral interferences with this Rhodium standard?
Rhodium has minimal spectral overlaps, but potential interferences may occur with ruthenium (Ru) at certain wavelengths. Always verify your instrument’s specific interference profile during method development.
5. How does the certification process ensure accuracy?
Each batch undergoes multi-point calibration using NIST-traceable reference materials, with the final concentration verified through independent ICP-MS analysis by accredited laboratories before certification.
