FAQs
What makes CMOS grade nitric acid different from regular lab grade?
CMOS grade undergoes additional purification to remove metallic impurities that could interfere with semiconductor manufacturing processes. It typically contains less than 1 ppm of critical metals compared to standard grades that may have 10-100 ppm.
Can I use this nitric acid for general lab cleaning?
While it’s pure enough for cleaning, its high purity makes it more expensive than necessary for routine cleaning tasks. Consider standard lab grade for general cleaning and reserve this CMOS grade for sensitive applications.
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.
Is this product suitable for ICP-MS sample preparation?
Yes, its low metal content makes it ideal for trace metal analysis. However, always perform appropriate blanks to account for any potential background contamination.
How should I dilute this 70% nitric acid for my application?
Always add acid to water slowly while stirring. For most lab applications, a 1:1 dilution with deionized water creates a 35% solution. For semiconductor etching, follow your specific process requirements which may call for different concentrations.
