Each batch undergoes rigorous quality control, including multi-point calibration verification, to guarantee compliance with international reference material standards. The 1000µg/ml concentration provides optimal flexibility for dilution, accommodating a wide range of analytical protocols without sacrificing sensitivity. Whether used as a primary standard or for routine instrument calibration, this solution minimizes systematic errors, enhancing the robustness of quantitative measurements. The Specpure® designation signifies adherence to the highest industry benchmarks, ensuring compatibility with ISO, ASTM, and EPA methodologies.
FAQs
1. What is the shelf life of this antimony plasma 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. Once opened, use within 6 months for optimal accuracy.
2. Is this solution compatible with organic solvent-based sample preparation?
While primarily designed for aqueous systems, the solution can be diluted with compatible organic solvents like methanol or acetone, provided the final matrix does not exceed 10% organic content to prevent precipitation or instrument damage.
3. Can this standard be used for environmental water testing?
Yes, the ultra-high purity and low matrix interference make it suitable for environmental applications, including surface water, groundwater, and wastewater analysis, provided proper dilution protocols are followed to match expected analyte concentrations.
4. What alternatives exist if I need a lower concentration?
For lower concentrations, the solution can be serially diluted using high-purity deionized water (18.2 MΩ·cm) or matrix-matched diluents, ensuring the final solution maintains homogeneity and stability for at least 30 days when stored refrigerated.
5. How should I handle potential contamination during aliquoting?
Use Class A volumetric pipettes or micropipettes with dedicated tips to prevent cross-contamination. Rinse pipettes with 1% nitric acid followed by deionized water between uses, and work in a laminar flow hood if ultra-trace analysis is required.
