Product Name – Indium, 1000 ppm ICP-ML, single-element standard
Quantity/Pack Size – 100 ml
Form – Liquid (aqueous solution in 2% HNO₃)
Grade – ICP-ML (Mass Spectrometry Grade)
Application – Elemental analysis, instrument calibration, trace metal testing
Product Overview
This 1000 ppm Indium single-element standard is meticulously prepared for inductively coupled plasma mass spectrometry (ICP-ML) applications, offering exceptional purity and stability in a 2% nitric acid matrix. The solution undergoes rigorous quality control to ensure ±1% concentration accuracy, with full NIST traceability for reliable analytical results. Packaged in high-density polyethylene bottles to prevent contamination, the standard maintains integrity for 24 months when stored properly. Its ultra-low background interference makes it particularly suitable for trace-level indium determinations in complex matrices. The solution’s homogeneous composition eliminates settling issues common in particulate standards, while the nitric acid base ensures compatibility with most ICP sample introduction systems. Each batch is accompanied by a comprehensive certificate of analysis detailing elemental impurities, density measurements, and stability data under varying temperature conditions.
FAQs
1. What is the matrix composition of this Indium standard?
The standard is prepared in 2% high-purity nitric acid (HNO₃) using Type I deionized water, with residual metal content below 10 ppt for most elements.
2. How does the concentration accuracy compare to other brands?
Our 1000 ppm Indium standard maintains ±1% concentration accuracy through gravimetric preparation methods, verified by independent third-party testing against NIST SRM 3100 series standards.
3. What materials are used for the bottle and cap?
The solution comes in HDPE bottles with PP caps, both tested for leachables and extractables to ensure no contamination of the standard over its shelf life.
4. Can this standard be used for ICP-OES applications?
While optimized for ICP-ML, the standard’s purity and concentration make it suitable for ICP-OES applications when appropriate dilution factors are applied for the higher detection limits of optical emission spectrometry.
5. What’s the typical lead time for custom concentrations?
Custom indium standards at different concentrations typically require 10-12 business days for preparation and quality certification, with expedited options available for urgent requirements.
