Product Overview
This Rhenium 1000 ppm ICP-ML single-element standard is meticulously formulated for high-precision trace elemental analysis, offering exceptional stability and accuracy in ICP-MS and ICP-OES applications. The standard is prepared in a 2% nitric acid matrix to ensure complete solubility and long-term stability, eliminating precipitation risks during storage or dilution. Each batch undergoes rigorous quality control, with traceability to NIST SRM standards, guaranteeing reliable and reproducible results for demanding analytical workflows. The low matrix interference and ultra-pure composition minimize background noise, enhancing detection limits for rhenium in complex samples. Packaged in high-density polyethylene (HDPE) bottles, the solution resists contamination and UV degradation, preserving integrity even in fluctuating lab conditions. The concentration is certified via gravimetric and volumetric methods, with uncertainty values provided for compliance with ISO/IEC 17025 standards. Ideal for laboratories requiring high-accuracy calibration curves, this standard ensures consistency across instruments and operators, reducing variability in multi-user environments.
FAQs
1. What is the shelf life of this Rhenium 1000 ppm standard when unopened?
The unopened standard remains stable for 24 months from the date of manufacture when stored at 15–25°C in its original packaging. Avoid exposure to direct sunlight or temperature extremes to prevent degradation of the nitric acid matrix.
2. Can this standard be used for both ICP-MS and ICP-OES applications?
Yes, the 1000 ppm concentration is optimized for dilution to working ranges suitable for both ICP-MS (typically ppb levels) and ICP-OES (ppm levels). The nitric acid matrix ensures compatibility with plasma-based techniques without additional sample preparation.
3. Is this standard compatible with organic solvents for sample preparation?
No, this aqueous standard is designed for direct dilution in water or dilute nitric acid. Mixing with organic solvents may cause phase separation or precipitation. For organic matrices, consider a rhenium standard in a compatible solvent like methanol or toluene.
4. How should I handle potential contamination during dilution?
Use Class A volumetric glassware and ultrapure water (18.2 MΩ·cm) to minimize contamination. Pre-rinse all containers with dilute nitric acid (1–2%) before use. Avoid pipettes with metal parts, as rhenium can adsorb onto surfaces.
5. What alternatives exist for lower concentration rhenium standards?
For sub-ppm requirements, consider our 10 ppm or 100 ppm rhenium standards, which offer similar matrix composition and traceability. These are ideal for environmental or biological samples where rhenium concentrations are naturally low.
