Product Name – Manganese standard solution, 1 g/L AAS single-element standard
Quantity/Pack Size – 500 ml
Form – Liquid
Grade – Analytical
Application – Atomic Absorption Spectroscopy (AAS)
Product Overview
This manganese standard solution is a high-precision 1g/L concentration specifically formulated for atomic absorption spectroscopy (AAS) applications. The solution is prepared using ultra-pure manganese salts dissolved in a stabilized matrix to prevent precipitation and ensure long-term stability. Each batch undergoes rigorous quality control to guarantee accuracy within ±0.5% of the stated concentration, making it ideal for calibration curves and quantitative analysis. The solution is packaged in a high-density polyethylene (HDPE) bottle with a tamper-evident seal to maintain integrity during storage and handling. The analytical grade purity ensures minimal interference from trace contaminants, while the single-element formulation eliminates cross-contamination risks common in multi-element standards. Compatible with most AAS instruments, this standard solution provides consistent performance across various wavelength settings. The 500ml pack size offers an optimal balance between cost efficiency and laboratory convenience, reducing frequent replenishment needs while maintaining freshness.
FAQs
1. What is the shelf life of this manganese 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. Can this standard be used with flame and graphite furnace AAS?
Yes, the solution is compatible with both flame and graphite furnace atomic absorption spectroscopy techniques without requiring additional preparation.
3. What is the matrix composition of this standard solution?
The solution uses a nitric acid matrix (typically 2-5% v/v) to stabilize the manganese ions and prevent precipitation over extended storage periods.
4. How should I handle potential contamination during use?
Use dedicated, acid-washed volumetric pipettes or dispensers to avoid cross-contamination, and always replace the cap immediately after use to minimize exposure to atmospheric moisture.
5. Is this solution traceable to NIST or other international standards?
The concentration is verified against certified reference materials and follows ISO 17034 guidelines for reference material production, though direct NIST traceability would require additional certification.
