Product Overview
This Specpure® platinum plasma standard solution delivers exceptional purity and consistency for critical trace metal analysis. Formulated at a precise 1000µg/ml concentration in a stabilized nitric acid matrix, it ensures minimal interference and maximum accuracy in spectroscopic techniques like ICP-MS and AAS. The solution undergoes rigorous quality control to maintain lot-to-lot reproducibility, with impurity levels strictly controlled to sub-ppm thresholds. Its ultra-low background contamination makes it particularly suitable for environmental testing, geological analysis, and high-sensitivity applications where platinum quantification demands absolute reliability. The Specpure® grade certification guarantees compliance with international standards for reference materials, while the acidified matrix enhances long-term stability and prevents analyte precipitation. Each batch is accompanied by a comprehensive certificate of analysis detailing exact concentration values and impurity profiles, allowing for seamless integration into existing calibration protocols without requiring additional validation steps.
FAQs
1. What is the shelf life of this platinum standard solution when stored properly?
When stored unopened at controlled room temperature (15-25°C) away from direct light, this solution maintains its certified concentration for 24 months from the date of manufacture. Once opened, we recommend using within 12 months for optimal accuracy.
2. Can this standard be used directly for ICP-OES analysis without dilution?
The 1000µg/ml concentration is typically too high for direct ICP-OES analysis and usually requires dilution. For most ICP-OES applications, a working range of 1-100µg/ml is recommended, so you would need to prepare appropriate dilutions using high-purity acids and deionized water.
3. What type of container material is used for packaging this solution?
The solution is packaged in high-density polyethylene (HDPE) bottles that have been pre-cleaned and tested for metal leaching. The caps are made of polypropylene with a PTFE liner to prevent contamination and ensure chemical compatibility with the nitric acid matrix.
4. How does the Specpure® grade differ from regular analytical grade standards?
Specpure® standards undergo additional purification steps and more stringent quality control compared to regular analytical grade. They feature lower background contamination (typically <10ppt for most interfering elements), tighter concentration tolerances (±0.5%), and more comprehensive certification documentation including multi-element impurity analysis.
5. What safety precautions should be taken when handling this nitric acid-based solution?
Always wear appropriate PPE including nitrile gloves, safety goggles, and a lab coat when handling. Work in a fume hood due to the nitric acid content. In case of skin contact, immediately rinse with plenty of water. The solution should be neutralized before disposal according to local hazardous waste regulations.
