Product Overview
This Specpure® tin plasma standard solution delivers 1000µg/ml concentration in a stable, acidified matrix, engineered for exceptional accuracy in plasma spectrometry applications. The ultra-high purity grade eliminates matrix interferences, ensuring reliable calibration curves and trace-level detection in ICP-OES and AAS workflows. Each batch undergoes rigorous multi-element analysis to guarantee consistency, with certification traceable to NIST standards. The solution’s extended shelf life (when stored properly) minimizes waste, while its ready-to-use formulation reduces preparation time. The Specpure® designation signifies a minimum 99.999% purity for the tin component, with contaminants controlled to sub-ppb levels. Packaged in HDPE bottles with tamper-evident seals, the solution resists leaching and contamination. Compatibility with most autosamplers and nebulizers makes it ideal for high-throughput laboratories, while the 1000µg/ml concentration allows flexible dilution for custom working ranges. The acidified matrix (typically 2-5% HNO₃) prevents precipitation and microbial growth, maintaining integrity during prolonged storage.
FAQs
1. What is the matrix composition of this tin standard solution?
The solution is typically prepared in 2-5% nitric acid (HNO₃) to ensure complete dissolution and long-term stability of the tin ions. The exact acid concentration is specified in the certificate of analysis provided with each batch.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
While primarily designed for ICP-OES, the ultra-high purity (Specpure® grade) makes it suitable for ICP-MS when diluted appropriately. However, for ICP-MS, we recommend verifying the acid matrix compatibility with your instrument’s introduction system, as high acid concentrations may affect sensitivity.
3. How should I store this solution to maintain its certified concentration?
Store the unopened bottle at 15-25°C in its original packaging, away from direct sunlight and sources of heat. Once opened, tightly recap the bottle after each use and store upright to prevent leakage. Under these conditions, the solution remains stable for at least 12 months from the date of manufacture.
4. Is this standard traceable to international reference materials?
Yes, each batch is traceable to NIST (National Institute of Standards and Technology) reference materials through an unbroken chain of comparisons. The certificate of analysis includes the traceability statement and uncertainty calculations for the certified concentration.
5. What alternatives are available if I need a lower concentration?
For lower concentrations, you can prepare working standards by serial dilution using high-purity diluents (e.g., 2% HNO₃). Alternatively, we offer tin standards at 100µg/ml and 10µg/ml concentrations in the same Specpure® grade for applications requiring ready-to-use lower concentrations.
