Product Overview
This 10000 ppm Tin ICP single-element standard in hydrochloric acid matrix is engineered for high-precision trace metal analysis in spectroscopic applications. The solution is prepared using ultra-pure tin metal dissolved in high-purity hydrochloric acid, ensuring minimal matrix interference and maximum stability. The concentration is certified against NIST-traceable reference materials, providing reliable calibration for ICP-OES and ICP-MS instrumentation. The acidic matrix (HCl) maintains tin in solution while preventing precipitation or adsorption losses, critical for long-term stability. Packaged in HDPE bottles to minimize leachables, this standard eliminates contamination risks during storage. The formulation includes proprietary stabilizers to prevent oxidation or hydrolysis, extending shelf life without compromising accuracy. Each batch undergoes rigorous homogeneity testing to ensure uniform distribution of tin throughout the solution. The low background impurity profile (<1 ppb for most common interferents) makes it suitable for ultra-trace analysis. Compatible with most autosamplers and nebulizer systems, this standard requires no additional preparation before use.
FAQs
1. What is the exact matrix composition of this tin standard?
The standard is prepared in 2-5% v/v hydrochloric acid (HCl) as the primary matrix, with proprietary stabilizers to maintain tin solubility and prevent hydrolysis. The exact HCl concentration is optimized for compatibility with most ICP instruments while minimizing polyatomic interferences.
2. Can this standard be used for mercury cold vapor analysis?
No, this tin standard is specifically formulated for ICP applications. Mercury cold vapor analysis requires different matrix conditions (typically nitric acid) and reduction chemistry that isn’t compatible with this tin standard’s composition.
3. What is the typical shelf life after opening the bottle?
When stored at 15-25°C in the original tightly sealed HDPE bottle, the standard remains stable for at least 12 months after opening. The acidic matrix and stabilizers prevent tin precipitation, but we recommend recapping immediately after use to minimize contamination risks.
4. Are there any known spectral interferences with this tin standard?
The primary tin isotopes (118, 120) may experience minor interferences from molybdenum oxides in some plasma conditions. The HCl matrix produces minimal polyatomic interferences, but we recommend checking your instrument’s interference correction equations for tin analysis in acidic matrices.
5. How does the concentration compare to tin standards from other suppliers?
This 10000 ppm concentration is industry-standard for single-element tin ICP standards. The key differentiators are our lower impurity profile (<1 ppb for most common interferents) and the proprietary stabilization system that maintains homogeneity without requiring sonication before use, unlike some competing products.
