Product Overview
This Tantalum plasma standard solution from Specpure® delivers exceptional purity and consistency, formulated at a concentration of 10,000µg/ml for high-performance analytical applications. The solution is prepared using ultra-pure Tantalum metal dissolved in a stabilized matrix, ensuring minimal interference and maximum accuracy in spectroscopic techniques like ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) and AAS (Atomic Absorption Spectroscopy). The Specpure® grade guarantees traceability and reliability, making it ideal for calibration curves, quality control, and research requiring precise metal quantification. The aqueous-based formulation ensures compatibility with most standard laboratory instrumentation, while the stable shelf life reduces the need for frequent recalibration. Each batch undergoes rigorous testing to confirm concentration accuracy and absence of contaminants, providing researchers with confidence in their analytical results. The solution is packaged in high-density polyethylene (HDPE) bottles to prevent leaching and maintain integrity during storage. Whether used in routine lab testing or advanced research, this standard solution offers the precision and reproducibility demanded by modern analytical chemistry.
FAQs
1. What is the shelf life of this Tantalum plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15–25°C) and protected from light. Once opened, use within 6 months for optimal accuracy.
2. Is this solution compatible with ICP-MS (Inductively Coupled Plasma Mass Spectrometry)?
While primarily designed for ICP-OES and AAS, this solution can be used for ICP-MS after appropriate dilution to avoid matrix effects and instrument saturation due to its high concentration.
3. Are there lower concentration alternatives available for Tantalum standards?
Lower concentrations (e.g., 1,000µg/ml or 100µg/ml) are typically prepared by serial dilution of this 10,000µg/ml stock solution using high-purity acids or deionized water, depending on the application.
4. What precautions should be taken during storage to maintain accuracy?
Store the bottle tightly sealed in a cool, dry place away from direct sunlight and heat sources. Avoid freezing, as it may alter the solution’s homogeneity. Always use clean, dedicated pipettes to prevent cross-contamination.
5. Does this solution contain any stabilizers or preservatives?
The solution is stabilized with high-purity nitric acid to prevent hydrolysis and precipitation, ensuring long-term homogeneity without additional preservatives that could interfere with analysis.
