Product Overview
This Terbium plasma standard solution (10,000µg/ml) from Specpure® delivers exceptional purity and stability for demanding spectroscopic applications. Formulated in a high-grade acid matrix, it minimizes matrix interferences while ensuring long-term stability and batch-to-batch consistency. The solution is rigorously tested for elemental impurities, with certified concentrations traceable to NIST standards, making it ideal for creating calibration curves or validating analytical methods. Its low particulate content and homogeneous composition prevent clogging in nebulizers or spray chambers, ensuring reliable performance in plasma-based techniques. The Specpure® grade guarantees minimal background contamination, critical for ultra-trace analysis where sensitivity is paramount. Each batch undergoes multi-point quality checks, including ICP-OES verification, to confirm the stated 10,000µg/ml concentration. The solution’s extended shelf life (when stored properly) reduces frequency of recalibration, improving lab efficiency. Compatible with most autosamplers and dilution systems, it integrates seamlessly into automated workflows without requiring additional pretreatment.
FAQs
1. What is the shelf life of this Terbium standard solution when unopened?
The unopened solution remains stable for 24 months from the date of manufacture when stored at 15–25°C in its original container. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the solution is optimized for both techniques. For ICP-MS, ensure the acid matrix (typically nitric acid) is compatible with your instrument’s introduction system to prevent cone corrosion.
3. What diluent is recommended for preparing lower concentration standards?
Use 2% v/v high-purity nitric acid (trace metal grade) or deionized water (18.2 MΩ·cm) for dilutions. Avoid hydrochloric or sulfuric acid unless your method specifically requires them.
4. How does the Specpure® grade differ from standard analytical grades?
Specpure® undergoes additional purification steps to reduce trace contaminants (e.g., other rare earth elements) below 10 ppb, ensuring minimal spectral interference in high-sensitivity applications.
5. Is this solution compatible with organic solvents for specific applications?
No, this aqueous standard is not designed for organic solvent compatibility. For organometallic applications, consider a Terbium standard dissolved in a suitable organic matrix like xylene or toluene.
