Product Overview
This Specpure® multi-element plasma standard solution is engineered for laboratories demanding uncompromising accuracy in trace metal analysis. The solution contains 21 certified elements—including thallium (400 µg/g), bismuth/indium/lead (200 µg/g each), and ultralow-concentration beryllium/strontium (1 µg/g)—dissolved in a 5% nitric acid matrix to ensure long-term stability and minimal matrix interference. Each element is independently verified against NIST-traceable reference materials, eliminating systematic errors in ICP-OES, AAS, or ICP-MS workflows. The ultra-high purity grade (Specpure®) guarantees negligible background contamination, critical for sub-ppb detection limits in environmental monitoring, pharmaceutical quality control, or advanced materials research. The solution’s homogeneous composition and extended shelf life (when stored at 15–25°C) reduce recalibration frequency, while the acidified matrix prevents elemental precipitation or adsorption to container walls. Compatible with most autodilution systems, this standard eliminates the need for in-house preparation, saving time and reducing human error in routine lab operations.
FAQs
1. What is the exact nitric acid concentration in this multi-element standard?
The solution uses a 5% (v/v) ultra-pure nitric acid matrix, optimized to balance elemental solubility and instrument compatibility without introducing spectral interferences.
2. Can this standard be used directly for ICP-MS without further dilution?
Direct use depends on your instrument’s linear range; most elements here are at ppm levels. For ICP-MS, dilution to ppb ranges (e.g., 1:1000) is typically required to avoid detector saturation.
3. How does the Specpure® grade differ from standard analytical-grade solutions?
Specpure® standards undergo additional purification steps to remove trace contaminants (e.g., <10 ppt for common interferents like Na, K, Ca), ensuring baseline stability for ultralow detection limits.
4. What container material is recommended for long-term storage to prevent leaching?
The solution is supplied in HDPE bottles, but for storage beyond 12 months, transfer to PTFE or PFA containers to minimize potential metal leaching from plastic.
5. Are the elemental concentrations certified individually or as a composite?
Each element is certified independently via multiple analytical techniques (ICP-OES, ID-MS), with uncertainties reported at 95% confidence intervals in the included COA.
