Product Name – Gold, 10 ppm ICP-ML, single-element standard
Quantity/Pack Size – 100 ml
Form – Liquid (aqueous solution)
Grade – ICP-ML (Inductively Coupled Plasma-Mass Spectrometry)
Application – Trace metal analysis, calibration, and quality control
Product Overview
This 10 ppm gold single-element ICP-ML standard is engineered for high-precision trace metal analysis, offering exceptional stability and accuracy in laboratory applications. The aqueous solution is prepared using ultra-pure gold (Au) with a concentration of 10 µg/ml, ensuring reliable calibration and quality control in ICP-MS workflows. The standard is manufactured under stringent quality protocols, with NIST-traceable certification to guarantee consistency across batches. Its low matrix interference and long-term stability make it suitable for demanding analytical environments where reproducibility is critical. The solution is packaged in a high-density polyethylene (HDPE) bottle to prevent contamination and degradation, maintaining integrity during storage and handling. Compatible with most ICP-MS instruments, this standard eliminates the need for in-house dilution, reducing preparation time and potential errors. The absence of preservatives ensures minimal spectral interference, while the acidified matrix (typically 2% HNO₃) enhances solubility and prevents precipitation. Whether used for routine calibration or method validation, this gold standard delivers uncompromised performance for laboratories prioritizing accuracy in elemental analysis.
FAQs
1. What is the shelf life of this 10 ppm gold ICP standard?
The standard remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15–25°C) and protected from light. Once opened, use within 6 months for optimal accuracy.
2. Is this standard compatible with ICP-OES instruments?
While optimized for ICP-MS, this 10 ppm gold standard can be used with ICP-OES, though sensitivity may vary. For ICP-OES applications, higher concentration standards (e.g., 100 ppm or 1,000 ppm) are typically recommended for better signal-to-noise ratios.
3. Are there alternatives to this single-element gold standard for multi-element analysis?
For multi-element analysis, consider a custom multi-element ICP standard containing gold alongside other target metals. Eqipped offers pre-mixed multi-element standards with gold at comparable concentrations for streamlined workflows.
4. What precautions should be taken during storage to maintain accuracy?
Store the bottle upright in a cool, dry place away from direct sunlight and heat sources. Avoid freezing, as it may alter the solution’s homogeneity. Always recap tightly after use to prevent evaporation or contamination.
5. How is the concentration of 10 ppm verified in this standard?
The concentration is verified using gravimetric preparation with high-purity gold metal, followed by validation via ICP-MS against NIST-traceable reference materials. Each batch includes a certificate of analysis (CoA) detailing the verification process.
