Product Overview

This Specpure® silicon plasma standard solution delivers exceptional purity and accuracy for demanding analytical applications. With a precise 10,000µg/ml silicon concentration in a stable aqueous matrix, it ensures reliable calibration and quantification in plasma-based techniques. The Specpure® grade guarantees minimal interference from trace contaminants, making it ideal for high-sensitivity measurements. The solution is prepared using ultra-pure reagents and undergoes rigorous quality control to meet international standards. Its long-term stability and homogeneous composition eliminate variability in results, while the convenient pack sizes (50ml, 100ml, 500ml) accommodate different laboratory workflows. The solution’s low acidity prevents instrument corrosion while maintaining analyte stability. Each batch is accompanied by a certificate of analysis detailing the exact concentration and impurity profile. This standard is particularly valuable for laboratories requiring NIST-traceable reference materials for silicon quantification in environmental, geological, or industrial samples.

FAQs

1. What is the shelf life of this silicon plasma standard solution?

The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature. Once opened, use within 6 months for optimal accuracy.

2. Can this standard be used for both ICP-OES and ICP-MS applications?

While primarily designed for ICP-OES, the solution’s high purity makes it suitable for ICP-MS applications when properly diluted to match the instrument’s working range.

3. What acid matrix is used in this standard solution?

The solution uses a dilute nitric acid matrix (typically 2-5%) to maintain silicon solubility and stability without interfering with most analytical methods.

4. How should I handle potential contamination when using this standard?

Use dedicated, acid-washed glassware and pipettes to prevent cross-contamination. Always work in a clean environment and avoid contact with metal surfaces.

5. What documentation is provided with this standard solution?

Each bottle includes a certificate of analysis with batch-specific data including exact concentration, expiry date, and impurity profile for traceability.
