Product Overview
This Cerium AAS standard solution delivers unmatched precision for atomic absorption spectroscopy, formulated with Specpure® grade purity to eliminate contaminants that could skew analytical results. The 1000µg/ml concentration ensures optimal sensitivity for detecting trace cerium levels, while the stabilized aqueous matrix prevents precipitation or degradation over time. Engineered for compatibility with most AAS instruments, this solution undergoes rigorous quality control to guarantee lot-to-lot consistency, with certified traceability to NIST standards. The low-acidity formulation minimizes instrument corrosion, extending the lifespan of nebulizers and burners. Each batch is supplied with a comprehensive certificate of analysis detailing exact cerium content, potential interferents, and expiration data. The solution’s clarity and stability make it ideal for both routine calibration and complex research applications where reproducibility is critical. Packaged in HDPE bottles with tamper-evident seals, it resists leaching and contamination during storage. For laboratories requiring ultra-low detection limits, this standard solution reduces background noise and improves signal-to-noise ratios in cerium quantification.
FAQs
1. What is the shelf life of this Cerium AAS standard solution when unopened?
The unopened solution maintains stability for 24 months from the date of manufacture when stored at 15-25°C in its original packaging. Always verify the expiration date on the certificate of analysis.
2. Can this solution be used with ICP-OES or only AAS instruments?
While optimized for AAS, the high purity makes it compatible with ICP-OES systems, though you may need to adjust dilution factors based on your instrument’s sensitivity requirements and plasma conditions.
3. What diluent is recommended for preparing lower concentration standards?
Use 1% v/v nitric acid (prepared from ultra-pure HNO₃) or deionized water (18.2 MΩ·cm) for dilutions. Avoid hydrochloric acid as it may introduce chloride interference in cerium analysis.
4. How does the Specpure® grade differ from standard analytical grades?
Specpure® undergoes additional purification steps to remove metallic and anionic impurities below 10 ppb, ensuring minimal spectral interference. Standard grades typically contain higher residual contaminants that can affect baseline stability.
5. What precautions should be taken when handling this solution?
Wear nitrile gloves and safety goggles, as the solution contains nitric acid. Work in a fume hood when preparing dilutions, and avoid skin contact to prevent irritation from trace acidity.
