Product Overview

This Ytterbium AAS standard solution (1000µg/ml) from Specpure® delivers exceptional purity and consistency for demanding analytical applications. Formulated using ultra-high-purity ytterbium in a stabilized aqueous matrix, it eliminates matrix interferences and ensures long-term stability without precipitation or concentration drift. The Specpure® grade guarantees minimal trace impurities, making it ideal for calibration curves, quality control checks, and low-level ytterbium quantification in complex samples. Each batch undergoes rigorous multi-element analysis to confirm absence of spectral overlaps with common interferents like lanthanides or transition metals. The solution’s homogeneous composition allows for direct dilution without requiring additional stabilizers, while its acidified base (typically nitric acid) prevents microbial growth and container leaching. Compatible with most AAS and ICP-OES instruments, this standard adheres to international metrological traceability protocols, with concentration values verified against NIST-certified reference materials. The amber glass packaging with PTFE-lined caps ensures protection from light-induced degradation and contamination during storage or repeated use.

FAQs

1. What is the shelf life of this Ytterbium 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 and reseal tightly after each use to prevent evaporation or contamination.

2. Can this standard be used for ICP-MS analysis?

While primarily designed for AAS, the Specpure® grade’s low impurity profile makes it suitable for ICP-MS applications. However, you may need to account for the nitric acid matrix and potential polyatomic interferences depending on your instrument’s mass resolution.

3. What diluent is recommended for preparing lower concentration standards?

Use 2% v/v high-purity nitric acid (trace metal grade) as the diluent to maintain matrix consistency. Avoid deionized water alone, as it may lead to hydrolysis or adsorption losses at ultra-low concentrations.

4. How does the Specpure® grade differ from standard AAS-grade solutions?

Specpure® undergoes additional purification steps to reduce background impurities (e.g., <10 ppb for most common interferents) and is certified for sub-ppb detection limits. Standard AAS grades typically allow higher impurity thresholds, which may affect baseline stability in sensitive analyses.

5. Is this solution compatible with automated sample handlers?

Yes, the solution’s viscosity and surface tension are optimized for compatibility with most automated dilution systems and autosamplers. However, rinse the system with 2% nitric acid between samples to prevent carryover, especially when analyzing high-concentration matrices.
