Product Description
Perchloric acid is a powerful mineral acid widely used in laboratories for its strong oxidizing properties and ability to dissolve metals. The 70% Suprapur grade from Merck ensures exceptional purity, making it ideal for sensitive analytical applications where trace metal contamination must be minimized.
This high-quality perchloric acid is commonly used in digestion processes for sample preparation, particularly in inorganic chemistry and environmental testing. Its low metal content (typically <0.01 ppm) makes it suitable for ICP-MS, AAS, and other trace analysis techniques where background interference must be eliminated.
When working with perchloric acid, proper safety measures are essential due to its corrosive and reactive nature. Always use in a properly ventilated fume hood with appropriate personal protective equipment (PPE).

FAQs
What is the difference between Suprapur and regular perchloric acid?
Suprapur grade perchloric acid undergoes additional purification steps to remove trace metal contaminants, making it suitable for high-sensitivity analytical applications where regular grades might introduce interference.
Can I use this perchloric acid for sample digestion?
Yes, this 70% Suprapur perchloric acid is ideal for digesting organic and biological samples prior to metal analysis, though proper safety protocols must be followed.
What safety equipment is required when handling perchloric acid?
Minimum requirements include a dedicated perchloric acid fume hood, acid-resistant gloves, face shield, and lab coat. Additional PPE may be needed depending on your specific application.
How should I store perchloric acid?
Store in a cool, dry place in its original container, away from organic materials, reducing agents, and direct sunlight. Always keep the container tightly sealed when not in use.
Is this perchloric acid suitable for ICP-MS analysis?
Yes, the Suprapur grade is specifically designed for trace metal analysis techniques like ICP-MS where ultra-low background contamination is critical for accurate results.
