Product Overview
This Caesium 10 ppm ICP-ML single-element standard is meticulously formulated to meet the stringent demands of modern analytical laboratories. Dissolved in a high-purity aqueous matrix, it delivers exceptional stability and homogeneity, eliminating matrix interference risks during ICP-MS or ICP-OES analysis. The 10 ppm concentration is optimized for calibration curves, method validation, and low-level detection protocols, ensuring linear response across dynamic ranges. Manufactured under ISO-compliant conditions, this standard undergoes rigorous multi-point quality checks—including ICP-OES verification—to guarantee lot-to-lot consistency. Its ultra-low background contamination profile (<1 ppt for common interferents like Na, K, Fe) makes it ideal for environmental, pharmaceutical, or materials science applications where trace-level accuracy is non-negotiable. The amber HDPE bottle with tamper-evident seal preserves integrity during storage, while the acidified matrix (2% HNO₃) prevents precipitation or microbial growth. Compatible with autosamplers and most ICP instrumentation, this standard reduces recalibration frequency, improving lab throughput without compromising data reliability.
FAQs
1. What is the shelf life of this Caesium 10 ppm ICP 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 fluctuations.
2. Can this standard be used for ICP-OES as well as ICP-MS applications?
Yes, the 10 ppm concentration is suitable for both ICP-OES and ICP-MS, though you may need to dilute it further for ICP-MS to avoid detector saturation, depending on your instrument’s linear range.
3. What is the matrix composition of this solution?
The standard is prepared in 2% high-purity nitric acid (HNO₃) using Type I water (18.2 MΩ·cm), ensuring minimal background interference and long-term stability of the Caesium ions.
4. Are there any known spectral interferences for Caesium at this concentration?
Caesium has minimal spectral overlaps, but high concentrations of barium (Ba) or rare earth elements may require mathematical correction. This standard’s purity minimizes such risks.
5. How should I dispose of unused or expired Caesium standard solution?
Follow local hazardous waste regulations. Neutralize with a compatible base (e.g., NaOH) before disposal, and consult your institution’s EHS guidelines for aqueous metal waste handling.
