Product Overview
This Multi-Element Plasma Standard Solution 2 is a Specpure®-certified reference material designed for precise instrumental calibration in plasma spectroscopy applications. Formulated with ultra-high-purity reagents, it contains potassium (K) at 10,000 µg/g, lithium (Li) at 250 µg/g, and sodium (Na) at 1,000 µg/g, ensuring accurate traceability for ICP-OES and atomic absorption spectroscopy (AAS) systems. The solution is stabilized in a matrix-compatible aqueous medium, minimizing matrix interference while maintaining long-term stability. Each batch undergoes rigorous quality control, including homogeneity testing and certification against NIST-traceable standards, to guarantee consistency and reliability in analytical workflows. The low-background formulation reduces contamination risks, making it ideal for high-sensitivity applications where precision is critical. Packaged in a 100ml HDPE bottle with a tamper-evident seal, the solution is ready for immediate use without requiring additional dilution for most standard calibration curves. Its Specpure® grade ensures compliance with ISO 17034 and ISO Guide 31, meeting the stringent requirements of research, industrial, and regulatory laboratories.
FAQs
1. What is the shelf life of this multi-element plasma 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 solution compatible with ICP-MS instrumentation?
While primarily designed for ICP-OES and AAS, it can be used for ICP-MS if diluted appropriately to avoid detector saturation from the high K concentration.
3. Are there alternatives with lower potassium concentrations available?
For applications requiring reduced K levels, consider our Multi-Element Plasma Standard Solution 1 (K @ 1,000 µg/g) or custom formulations upon request.
4. How should I store the solution after opening?
Store opened bottles tightly sealed at 2–8°C, protected from light. Avoid repeated freeze-thaw cycles to prevent degradation of the matrix.
5. Does this solution require acidification before use?
No additional acidification is needed. The solution is pre-stabilized with nitric acid (2% v/v) to maintain element solubility and prevent precipitation.
