Product Overview
NORMATOM® Ultrapure Hydrochloric Acid (32%) is a high-purity reagent engineered for laboratories demanding ultra-low contamination levels in critical applications. This trace-metal-free acid undergoes rigorous purification processes to eliminate impurities, ensuring consistent performance in sensitive analytical techniques such as ICP-MS, atomic absorption (AA) spectroscopy, and trace element analysis. The ultrapure grade minimizes background interference, making it indispensable for sample digestion, matrix dissolution, and preparation of calibration standards where precision is paramount. Its stable 32% concentration provides optimal reactivity without compromising purity, while the NORMATOM® certification guarantees adherence to stringent quality benchmarks. Packaged in high-density polyethylene (HDPE) containers to prevent leaching or external contamination, this acid maintains integrity throughout storage and handling. Whether used in environmental testing, pharmaceutical QC, or advanced research, its reliability reduces variability in results, streamlining workflows and enhancing reproducibility. The absence of metallic contaminants (e.g., Fe, Cu, Zn) below ppb levels ensures compatibility with ultra-trace methodologies, while its clear, colorless appearance confirms freedom from particulate matter. For laboratories prioritizing accuracy and repeatability, this ultrapure HCl delivers unmatched performance in demanding analytical environments.
FAQs
1. What is the difference between ultrapure and reagent-grade hydrochloric acid?
Ultrapure hydrochloric acid undergoes additional purification steps to remove trace metals and impurities, achieving ppb-level contamination control, whereas reagent-grade may contain higher residual metals, making it unsuitable for ultra-trace analysis.
2. Can this acid be used for digesting organic samples?
Yes, its 32% concentration and high purity make it effective for digesting organic matrices in applications like environmental sample preparation, though specific protocols should be followed for complete oxidation.
3. How should I store ultrapure hydrochloric acid to maintain its purity?
Store in a cool, ventilated area away from direct sunlight and incompatible substances. Keep the container tightly sealed in its original HDPE bottle to prevent contamination or moisture absorption.
4. Is this product compatible with ICP-OES or ICP-MS instrumentation?
Absolutely. The ultrapure grade is designed to minimize spectral interferences and background noise, ensuring accurate readings in ICP-OES and ICP-MS analyses.
5. What alternatives exist for applications requiring lower acid concentrations?
For diluted applications, consider preparing working solutions from this 32% stock using ultrapure water (18.2 MΩ·cm), or explore pre-diluted ultrapure HCl options if available.
