Product Overview
This Specpure® bromide standard solution delivers 1000µg/ml concentration with exceptional purity, designed specifically for ion chromatography applications where precision and reproducibility are critical. The solution is prepared using ultra-high-purity reagents and deionized water (18.2 MΩ·cm) to eliminate matrix interferences, ensuring accurate baseline resolution in chromatographic analysis. Each batch undergoes rigorous multi-point calibration against NIST-traceable reference materials, with certificates of analysis provided for full transparency. The stable formulation in high-density polyethylene (HDPE) bottles minimizes leaching and contamination risks during storage. Compatible with all major IC systems including Metrohm, Thermo Fisher, and Shimadzu, this standard eliminates the need for in-house preparation while maintaining ISO 17034 compliance. The 100ml and 500ml pack sizes offer flexibility for both routine calibration and high-throughput laboratories, with extended shelf life of 24 months when stored at 15-25°C.
FAQs
1. What is the exact matrix composition of this bromide standard solution?
The solution is prepared in ultra-pure water (18.2 MΩ·cm resistivity) with <0.1% v/v nitric acid as a stabilizer to prevent microbial growth and maintain ion integrity.
2. Can this standard be used with suppressed conductivity detection systems?
Yes, the solution is fully compatible with suppressed conductivity detectors as it contains no organic modifiers or buffer components that could interfere with suppression chemistry.
3. How does the Specpure® grade differ from analytical reagent grade?
Specpure® standards undergo additional purification steps including sub-boiling distillation and have stricter limits for trace metal contaminants (typically <10 ppt for most metals) compared to standard AR grade solutions.
4. What is the recommended procedure for preparing working standards from this solution?
For working standards, perform serial dilution using the same matrix as your samples (typically deionized water or your mobile phase) to maintain consistent ionic strength and pH conditions.
5. Are the HDPE bottles certified for low-level anion storage?
The bottles are manufactured from virgin HDPE resin that meets USP Class VI standards and have been tested for anion leaching, showing <0.5% change in bromide concentration over 12 months.
