Product Overview
This 10 ppm Gallium single-element standard is meticulously formulated for inductively coupled plasma-mass spectrometry (ICP-ML) applications, delivering exceptional purity and consistency for critical analytical workflows. The solution is prepared using ultra-high-purity gallium metal dissolved in a stabilized nitric acid matrix, ensuring long-term stability and resistance to contamination. Each batch undergoes rigorous multi-point calibration against NIST-traceable reference materials to guarantee concentration accuracy within ±2% tolerance. The low matrix interference profile makes it ideal for trace-level detection in complex sample matrices, while the acidified formulation prevents precipitation or adsorption losses during storage. Packaged in HDPE bottles with tamper-evident seals, the standard maintains integrity during transport and extended bench use. The 10 ppm concentration offers optimal sensitivity for most ICP-ML instruments without requiring additional dilution, though it remains compatible with further dilution protocols when needed. All production follows ISO 17034 and ISO/IEC 17025 guidelines, with comprehensive certificates of analysis provided for each lot, including detailed impurity profiles and expiration dating based on accelerated stability testing.
FAQs
1. What is the shelf life of this Gallium ICP standard when stored properly?
The standard remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C. Once opened, use within 12 months for optimal performance, though recertification is recommended if stored beyond this period.
2. Can this standard be used with ICP-OES instruments, or is it specifically for ICP-MS?
While optimized for ICP-MS applications, this 10 ppm standard is compatible with ICP-OES systems. You may need to adjust the working concentration range to match your OES instrument’s linear dynamic range for gallium detection.
3. What materials are used for the bottle and cap to prevent contamination?
The solution is packaged in high-density polyethylene (HDPE) bottles with polypropylene caps. Both materials are pre-cleaned using Class 100 cleanroom protocols and tested for trace metal leaching to ensure no detectable gallium contamination.
4. How should I prepare working standards from this 10 ppm solution?
For serial dilution, use ultra-pure water (18.2 MΩ·cm) and trace-metal-grade acids. A typical protocol involves preparing intermediate standards at 1 ppm and 100 ppb levels, then further diluting to your target concentrations using the same acid matrix as the original standard.
5. What certification documentation accompanies each bottle?
Every unit includes a multi-page certificate of analysis detailing the exact concentration, uncertainty values, method of preparation, traceability to NIST SRMs, impurity analysis (including 23 common interferents), and batch-specific storage recommendations.
