Product Overview
Sulfuric acid ULTREX® II Ultrapure reagent is a high-performance, ultra-low trace metal acid designed for demanding laboratory applications where contamination control is critical. This reagent-grade sulfuric acid undergoes rigorous purification processes to eliminate metallic impurities, ensuring consistent results in sensitive analytical techniques like ICP-MS and atomic absorption spectroscopy. Its exceptional purity makes it particularly suitable for semiconductor manufacturing, environmental testing, and advanced research protocols where even trace contamination could compromise data integrity. The ULTREX® II designation guarantees a product that meets the most stringent quality standards, with documented impurity profiles far exceeding conventional reagent grades. The acid maintains its stability under standard laboratory conditions, though proper handling procedures should always be followed due to its corrosive nature. This product represents the gold standard for applications requiring the highest possible purity in sulfuric acid, eliminating background interference that could affect analytical accuracy. The 500ml packaging provides an optimal balance between sufficient volume for regular use and freshness preservation, as the container is designed to minimize exposure to potential contaminants during storage and dispensing.
FAQs
1. What makes ULTREX® II sulfuric acid different from regular reagent grade?
ULTREX® II undergoes additional purification steps to reduce trace metal contaminants to parts-per-billion levels, unlike standard reagent grades which typically contain higher impurity levels that can interfere with sensitive analyses.
2. Can this sulfuric acid be used for sample digestion in ICP-MS?
Yes, its ultra-low trace metal content makes it ideal for sample preparation in ICP-MS applications where metal contamination from reagents must be minimized to ensure accurate elemental analysis.
3. What is the typical shelf life of this product when unopened?
When stored in its original container at room temperature, the product maintains its specified purity for at least 24 months from the date of manufacture.
4. Are there any special storage requirements beyond standard acid handling?
While standard acid storage protocols apply, it’s recommended to keep the container tightly sealed when not in use and store it away from direct sunlight to prevent potential degradation of the ultra-pure quality.
5. How does the purity of this product compare to semiconductor grade sulfuric acid?
ULTREX® II meets or exceeds semiconductor grade specifications for most applications, with comparable or better impurity profiles for critical metals like iron, copper, and zinc that are particularly problematic in electronics manufacturing.
