Product Overview
This Barium AAS standard solution (1000µg/ml) is formulated with Specpure® grade purity, ensuring minimal interference and maximum reliability in atomic absorption spectroscopy (AAS) applications. The solution is prepared using ultra-high-purity reagents and deionized water, meeting stringent quality control standards for trace metal analysis. Its stable concentration eliminates the need for frequent recalibration, saving valuable lab time while maintaining accuracy across experiments. The Specpure® designation guarantees low background contamination, making it ideal for sensitive analytical procedures where precision is critical. Packaged in high-density polyethylene (HDPE) bottles, the solution resists chemical degradation and external contamination, preserving its integrity throughout storage. Whether used for environmental testing, pharmaceutical analysis, or industrial quality control, this standard solution delivers consistent performance, reducing variability in results. The 1000µg/ml concentration provides flexibility for dilution, accommodating a wide range of analytical requirements without compromising accuracy.
FAQs
1. What is the shelf life of this Barium AAS standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature, away from direct sunlight and moisture.
2. Is this solution compatible with flame AAS and graphite furnace AAS?
Yes, the Specpure® grade ensures compatibility with both flame and graphite furnace AAS techniques, provided the instrument is properly calibrated for barium analysis.
3. Can this solution be used as a primary standard for calibration?
While it is highly pure, it is recommended to verify the concentration against a certified reference material (CRM) if used as a primary calibration standard for regulatory compliance.
4. What precautions should be taken during storage to maintain accuracy?
Store the bottle tightly sealed in a cool, dry place. Avoid exposure to temperature fluctuations, and ensure the cap is securely closed after each use to prevent evaporation or contamination.
5. Are there any known interferences when using this solution in AAS?
Common interferences for barium in AAS include sulfate, phosphate, and aluminum ions. Using a releasing agent like lanthanum chloride can mitigate these effects during analysis.
