Product Overview
This ICP multi-element standard solution contains 33 precisely formulated elements at 100 mg/L concentration, designed for high-accuracy calibration of ICP-MS and ICP-OES instruments. The solution is prepared using ultra-pure reagents and deionized water (18.2 MΩ·cm) to minimize matrix interference, ensuring reliable analytical results. Each element is certified for concentration accuracy with traceability to NIST reference materials, making it suitable for demanding laboratory applications. The solution is stabilized with high-purity nitric acid (2% v/v) to prevent precipitation and maintain long-term stability. Packaged in HDPE bottles with tamper-evident seals, it guarantees contamination-free storage and handling. The multi-element composition eliminates the need for multiple single-element standards, streamlining workflows while maintaining precision. Ideal for laboratories requiring consistent performance in trace metal analysis, environmental testing, or industrial quality control.
FAQs
1. What is the shelf life of this ICP multi-element standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C. Once opened, use within 6 months for optimal accuracy.
2. Is this standard compatible with both ICP-MS and ICP-OES instruments?
Yes, the 100 mg/L concentration is optimized for direct use in ICP-OES and can be diluted for ICP-MS applications, though matrix matching may be required for specific samples.
3. Are there lower-concentration alternatives available for this 33-element standard?
This product is specifically formulated at 100 mg/L. For lower concentrations, serial dilution using ultra-pure acids is recommended to maintain accuracy.
4. What precautions should be taken during storage to maintain integrity?
Store upright in the original bottle at room temperature (15-25°C), away from direct sunlight and moisture. Avoid freezing, as it may alter the solution’s homogeneity.
5. How is the concentration of each element verified in this standard?
Concentrations are verified using primary reference materials traceable to NIST, with certification provided for each element through gravimetric and volumetric analysis.
