Product Overview
This Specpure® tin plasma standard solution delivers exceptional purity and consistency for demanding analytical applications, featuring a certified tin concentration of 10,000µg/ml in a stabilized nitric acid matrix. Engineered for plasma spectroscopy techniques including ICP-OES and atomic absorption spectroscopy (AAS), the solution maintains long-term stability with minimal matrix interference, ensuring reliable calibration curves and quantitative analysis. The Specpure® grade guarantees ultra-low trace metal impurities, with each batch rigorously tested against NIST-traceable reference materials for absolute concentration accuracy. The solution’s homogeneous composition eliminates precipitation risks during storage or dilution, while its acidified formulation prevents microbial contamination. Packaged in high-density polyethylene bottles with tamper-evident seals, the standard resists leaching and maintains integrity across multiple freeze-thaw cycles. Its broad linear dynamic range accommodates both high-sensitivity environmental testing and industrial process control applications without requiring multiple dilutions. The accompanying certificate of analysis provides comprehensive elemental impurity data, expiration dating, and recommended storage protocols to maintain specification compliance throughout the product’s shelf life.
FAQs
1. What is the shelf life of this tin plasma standard solution when stored properly?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C in its original container, protected from light and moisture. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used directly for ICP-MS analysis without further dilution?
While suitable for ICP-OES and AAS, the 10,000µg/ml concentration is typically too high for direct ICP-MS use. We recommend serial dilution to the 1-100µg/ml range using ultra-pure nitric acid to match your instrument’s linear dynamic range.
3. What material are the bottles made from, and are they compatible with HF-containing samples?
The bottles are constructed from high-density polyethylene (HDPE), which offers excellent chemical resistance to nitric acid but is not compatible with hydrofluoric acid. For HF applications, transfer to PTFE containers immediately upon opening.
4. How does the Specpure® grade differ from standard analytical-grade plasma standards?
Specpure® standards undergo additional purification steps to achieve lower background impurity levels (typically <10ppt for most elements) compared to standard analytical grades. This reduces spectral interferences and improves detection limits in ultra-trace analysis.
5. What dilution protocol do you recommend for preparing working standards from this 10,000µg/ml solution?
For most applications, prepare intermediate standards at 1,000µg/ml and 100µg/ml by volumetric dilution using 2% nitric acid, then create working standards from these. Always use Class A volumetric glassware and perform dilutions in a laminar flow hood to minimize contamination.
