Product Overview
This ICP multi-element standard solution is a high-precision reference material containing 32 elements at a uniform concentration of 100 mg/L, designed for accurate calibration in inductively coupled plasma optical emission spectroscopy (ICP-OES) and atomic absorption spectroscopy (AAS). Formulated with ultra-pure reagents and stabilized in a nitric acid matrix, it ensures minimal interference and long-term stability. The solution undergoes rigorous quality control to guarantee traceability to NIST standards, making it ideal for laboratories requiring consistent, reliable results. Its broad elemental coverage—including alkali metals, transition metals, and rare earth elements—eliminates the need for multiple single-element standards, streamlining workflow efficiency. The high-purity grade minimizes background contamination, while the ready-to-use liquid form reduces preparation time. Compatible with most ICP-OES and AAS instruments, this standard solution is packaged in an amber glass bottle to prevent photodegradation, with a tamper-evident seal for integrity assurance. Whether for routine calibration or method validation, its precision and reproducibility make it a critical tool for analytical chemists and research professionals.
FAQs
1. What elements are included in this 32-element ICP standard solution?
The solution contains a balanced mix of 32 elements, including alkali metals (e.g., Na, K), alkaline earth metals (e.g., Ca, Mg), transition metals (e.g., Fe, Cu, Zn), and trace elements (e.g., As, Se, Pb), along with rare earth elements for comprehensive calibration.
2. Is this standard compatible with both ICP-OES and AAS instruments?
Yes, the 100 mg/L concentration and nitric acid matrix are optimized for compatibility with most ICP-OES and AAS systems, though dilution may be required for specific applications or instrument sensitivity ranges.
3. How should this standard be stored to maintain stability?
Store the unopened bottle at 15–25°C in its original packaging, away from direct sunlight and heat sources. Once opened, tightly recap and use within the recommended shelf life to prevent contamination or evaporation.
4. Are there lower-concentration alternatives available for trace analysis?
For trace-level applications, consider diluting this standard or exploring single-element standards at lower concentrations (e.g., 10 mg/L or 1 mg/L), though pre-diluted multi-element standards may also be available.
5. Does this standard require any preparation before use?
The solution is ready-to-use for most applications, but shaking gently before use is recommended to ensure homogeneity. For instruments with specific matrix requirements, further dilution with ultrapure water or acid may be necessary.
