Form – Liquid
Grade – ARISTAR® (Ultra-High Purity)
Application – Trace metal analysis, semiconductor etching, mineral digestion
Product Overview
Hydrofluoric acid (~48%) from the ARISTAR® range is a high-purity reagent specifically formulated for trace analysis applications where ultra-low contamination is critical. This lab-grade acid undergoes rigorous purification processes to ensure minimal metallic and anionic impurities, making it ideal for sensitive analytical techniques such as ICP-MS, AAS, and other trace-level determinations. The ~48% concentration provides an optimal balance between reactivity and handling safety, while the ARISTAR® certification guarantees consistent performance in demanding laboratory environments. Packaged in high-density polyethylene (HDPE) bottles to prevent leaching and contamination, this hydrofluoric acid maintains its integrity during storage and use. Its exceptional purity reduces background interference in analytical instruments, enabling more accurate and reliable data collection. The acid’s stability and controlled concentration ensure reproducibility across experiments, which is essential for research and quality control protocols. Proper handling with compatible lab equipment and safety measures is recommended due to its corrosive nature.
FAQs
1. What is the difference between ARISTAR® and standard hydrofluoric acid?
ARISTAR® hydrofluoric acid undergoes additional purification steps to remove trace metal contaminants, making it suitable for ultra-sensitive analytical applications where standard grades may introduce interference.
2. Can this hydrofluoric acid be used for semiconductor processing?
Yes, the high purity of this ARISTAR® grade makes it compatible with semiconductor etching and cleaning processes where residual impurities could affect device performance.
3. What precautions should be taken when storing this acid?
Store in a cool, well-ventilated area away from incompatible materials like glass or metals. Use HDPE or PTFE containers and ensure secondary containment to prevent spills.
4. Is this acid compatible with standard lab glassware?
No, hydrofluoric acid reacts with silica-based materials like glass. Always use PTFE, HDPE, or other HF-resistant labware for handling and storage.
5. How does the 48% concentration compare to other common HF concentrations?
The ~48% concentration offers a balance between reactivity and ease of handling. Lower concentrations (e.g., 10-20%) are less aggressive but may require larger volumes, while higher concentrations (e.g., 70%) are more hazardous and volatile.
