Product Overview
This Indium 10 ppm ICP-MS single-element standard delivers exceptional purity and consistency for demanding trace metal analysis applications. Formulated in a 2% nitric acid matrix, it ensures complete solubility and long-term stability, eliminating precipitation risks that could compromise analytical accuracy. The standard is rigorously tested against NIST-traceable reference materials to guarantee ±1% concentration accuracy, making it ideal for calibration curves, quality control checks, and method validation in ICP-MS workflows. Its low background impurity profile (<0.1 ppb for most common interferents) prevents spectral overlaps, while the amber glass packaging with PTFE-lined cap preserves integrity against light degradation and contamination. The solution's homogeneous composition allows for direct dilution without requiring additional stabilization steps. Each batch undergoes multi-point verification using high-resolution ICP-MS to confirm elemental purity and concentration uniformity across the entire volume. The accompanying Certificate of Analysis provides comprehensive lot-specific data including expiration date, storage conditions, and interference profiles for major analytical wavelengths.
FAQs
1. What is the shelf life of this Indium ICP-MS standard when unopened?
The unopened standard maintains its certified concentration for 24 months from the date of manufacture when stored at 15-25°C in its original packaging away from direct sunlight.
2. Can this standard be used for ICP-OES applications?
While primarily designed for ICP-MS, this 10 ppm Indium standard can be used for ICP-OES after appropriate dilution, though you may need to account for the nitric acid matrix effects at higher concentrations.
3. What dilution factors are recommended for preparing working standards?
For typical ICP-MS applications, we recommend serial dilutions using 2% HNO₃ to prepare working standards in the 0.1-100 ppb range, though optimal dilution depends on your instrument’s sensitivity and sample matrix.
4. How does the nitric acid concentration affect the standard’s performance?
The 2% HNO₃ matrix is optimized to balance element stability and instrument compatibility, preventing hydrolysis while minimizing plasma suppression effects in most ICP-MS systems.
5. What documentation is provided with each bottle?
Each unit includes a Certificate of Analysis detailing the exact concentration, uncertainty values, expiration date, storage instructions, and interference data for key analytical wavelengths.
