Product Overview

This Ytterbium plasma standard solution (10,000µg/ml) from Specpure® is engineered for precision in atomic spectroscopy applications, offering exceptional purity and stability for demanding analytical workflows. The solution is prepared in a high-purity nitric acid matrix (typically 2-5% v/v), ensuring compatibility with ICP-OES, ICP-MS, and AAS instrumentation while minimizing matrix interference. The Specpure® grade guarantees traceability to NIST standards, with certified impurity levels below 10 ppb for most metallic contaminants, making it ideal for ultra-trace analysis where background interference must be negligible. The solution’s homogeneous composition eliminates the need for pre-dilution shaking, while the amber glass packaging with PTFE-lined caps prevents contamination from leachables or ambient moisture. Each batch undergoes rigorous multi-element analysis via ICP-MS to verify concentration accuracy (±0.5% tolerance) and long-term stability (shelf life of 24 months when stored at 15-25°C). The 10,000µg/ml concentration provides a cost-effective stock for preparing working standards down to ppb levels, reducing dilution errors in routine lab operations. The nitric acid matrix is optimized to match common sample digestion protocols, ensuring seamless integration into existing analytical methods without requiring additional matrix matching adjustments.

FAQs

1. What is the exact nitric acid concentration in this Ytterbium standard solution?

The solution is stabilized in 2-5% v/v high-purity nitric acid, which is typical for plasma standards to ensure solubility and prevent hydrolysis of the Yb³⁺ ions. The exact concentration is batch-specific and listed on the Certificate of Analysis.

2. Can this standard be used directly for ICP-MS analysis without further dilution?

No, the 10,000µg/ml concentration is too high for direct ICP-MS analysis and will cause detector saturation. Typical working ranges for ICP-MS are 0.1-100 µg/ml, so dilution by a factor of 100-100,000x is required depending on your instrument’s linear range.

3. How does the Specpure® grade differ from standard analytical-grade Ytterbium solutions?

Specpure® standards undergo additional purification steps to reduce metallic impurities to <10 ppb, compared to typical analytical-grade solutions which may contain 100-1,000 ppb impurities. This is critical for ultra-trace analysis where background signals from contaminants like Fe, Cu, or Pb could interfere with low-level determinations.

4. What is the recommended storage protocol to maintain the solution’s stability?

Store the unopened bottle at 15-25°C in its original packaging, away from direct sunlight and sources of heat or ignition. After opening, tightly reseal the PTFE-lined cap and purge the headspace with argon if storing for >3 months. Avoid repeated freeze-thaw cycles, as this can degrade the matrix stability.

5. Are there any known spectral interferences for Ytterbium at this concentration in ICP-OES?

Yb has several strong emission lines (e.g., 328.937 nm, 369.419 nm), but potential overlaps may occur with Gd (328.986 nm) or Dy (369.516 nm) in complex matrices. Using high-resolution optics or alternative wavelengths (e.g., 241.667 nm) can mitigate this. Always verify with your specific instrument’s spectral library.
