Product Overview
This Dysprosium AAS standard solution from Specpure® delivers exceptional purity and consistency, formulated specifically for high-precision atomic absorption spectroscopy (AAS) and inductively coupled plasma optical emission spectrometry (ICP-OES). The 1000µg/ml concentration ensures optimal sensitivity and linearity across analytical ranges, eliminating dilution errors while maintaining traceability to NIST or equivalent standards. The Specpure® grade guarantees minimal matrix interference, with contaminant levels strictly controlled below ppb thresholds, making it ideal for ultra-trace analysis in research and industrial laboratories. The solution is stabilized in a high-purity acid matrix (typically nitric or hydrochloric acid) to prevent precipitation and ensure long-term stability, even under variable storage conditions. Each batch undergoes rigorous multi-element ICP-MS validation to certify accuracy, with a certificate of analysis (CoA) provided for lot-specific data, including expiry and recommended storage protocols. The amber glass packaging with PTFE-lined caps minimizes leaching and evaporation, preserving integrity from first use to last. Compatible with most AAS and ICP instruments, this standard eliminates the need for in-house preparation, reducing labor costs and human error while delivering reproducible results for critical applications like rare earth element quantification, environmental monitoring, or materials characterization.
FAQs
1. What is the shelf life of this Dysprosium AAS standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C. Once opened, use within 12 months or as specified in the CoA.
2. Can this standard be used for ICP-MS analysis?
While optimized for AAS/ICP-OES, it can be used for ICP-MS if further diluted to match the instrument’s linear range. Verify compatibility with your ICP-MS method for matrix effects.
3. What acid matrix is used in this solution?
The solution is typically stabilized in 2–5% high-purity nitric acid (HNO₃), though the exact composition is detailed in the accompanying CoA.
4. Is this standard traceable to NIST or other reference materials?
Yes, the concentration is traceable to NIST SRMs or equivalent primary standards, with uncertainty values provided in the certificate of analysis.
5. How should I dispose of unused Dysprosium standard solution?
Follow local hazardous waste regulations. Neutralize with a compatible base (e.g., NaOH) before disposal, or contact a licensed chemical waste handler for large volumes.
