Key Applications
This Suprapur nitric acid finds use in various laboratory procedures including:
Sample preparation for atomic absorption spectroscopy (AAS) and inductively coupled plasma (ICP) analysis
Digestion of biological and environmental samples for metal analysis
Cleaning and passivation of laboratory glassware and equipment
Preparation of standards and reagents for analytical chemistry
Etching and surface treatment in materials science research
Safety and Handling
Nitric acid is a strong oxidizing agent and requires careful handling. Always wear appropriate personal protective equipment including acid-resistant gloves, safety goggles, and a lab coat. Work in a properly ventilated fume hood and have neutralizers like sodium bicarbonate readily available in case of spills.
Store the bottle in a cool, dry place away from incompatible substances like organic materials, reducing agents, and alkalis. Keep the container tightly closed when not in use to prevent absorption of moisture and contamination.
Why This Grade Matters
Unlike technical or commercial grades, Suprapur nitric acid undergoes additional purification steps to remove trace metal contaminants. This makes it ideal for:
Analytical laboratories requiring ultra-low detection limits
Environmental testing where background contamination must be minimized
Pharmaceutical and food testing laboratories
Research institutions working with sensitive instrumentation
The 1 L packaging provides an optimal balance between convenience and shelf life, reducing the need for frequent reordering while maintaining freshness.
FAQs
What makes Suprapur nitric acid different from regular nitric acid?
Suprapur grade undergoes additional purification to remove trace metal impurities, making it suitable for sensitive analytical techniques where regular grades might introduce contamination.
Can I use this for cleaning lab glassware?
Yes, this high-purity acid is excellent for cleaning and passivating glassware, especially when preparing for trace metal analysis. Always rinse thoroughly with deionized water afterward.
What’s the shelf life of this product?
When stored properly in its original container at room temperature, this nitric acid maintains its specifications for at least 2 years from the date of manufacture.
Do you provide the certificate of analysis?
Yes, each bottle comes with a certificate of analysis from Merck. You can also request additional documentation when placing your order with eqipped.
Is this suitable for ICP-MS sample preparation?
Absolutely. The ultra-low metal content makes it ideal for ICP-MS applications where background contamination must be minimized for accurate results.
