Product Overview
This Specpure® Indium plasma standard solution delivers exceptional purity and stability for demanding spectroscopic applications. Formulated at a precise 10µg/ml concentration, it ensures reliable calibration curves in ICP-OES, ICP-MS, and AAS workflows. The solution is prepared from high-purity indium metal (99.999% min) and stabilized in a low-acid matrix to minimize interference. Each batch undergoes rigorous multi-element analysis to guarantee accuracy, with traceability to NIST SRMs. The aqueous formulation eliminates particulate contamination risks while maintaining long-term stability when stored properly. Its low matrix background makes it ideal for trace-level determinations in complex samples. The solution is supplied in a high-density polyethylene bottle with a tamper-evident seal to prevent contamination during storage and handling.
FAQs
1. What is the shelf life of this indium standard solution?
When stored unopened at 15-25°C in its original container, the solution maintains its certified concentration for 24 months from the date of manufacture. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for mercury analysis?
This is a single-element indium standard. For mercury analysis, you would need a mercury-specific standard solution, as indium cannot serve as a substitute for mercury calibration.
3. What acid matrix is used in this solution?
The solution uses a dilute nitric acid matrix (typically 2-5% v/v) to stabilize the indium ions and prevent precipitation while maintaining compatibility with most ICP instruments.
4. Is this solution compatible with organic solvents?
This aqueous standard is not designed for direct dilution with organic solvents. For organic-based applications, consider a standard prepared in an organic-soluble matrix or perform appropriate sample preparation techniques.
5. How should I dispose of unused solution?
Follow your institution’s chemical waste disposal protocols. As a heavy metal solution, it should be collected in designated containers and disposed of through authorized hazardous waste channels, not poured down drains.
