Product Overview
This Puratronic™ grade ammonium chloride delivers exceptional purity at 99.999% (metals basis), specifically engineered for applications demanding ultra-low trace metal contamination. The crystalline powder form ensures consistent dissolution and handling characteristics in laboratory environments. Unlike standard reagent grades, this material undergoes rigorous purification processes to eliminate metallic impurities that could interfere with sensitive analytical techniques. The high assay specification guarantees reliable performance in critical applications where even trace levels of contaminants can compromise results. The product’s stability under normal storage conditions makes it suitable for long-term use in controlled laboratory settings. Each batch is accompanied by comprehensive certification documentation verifying the trace metal analysis, providing researchers with complete confidence in the material’s purity profile. The carefully controlled particle size distribution further enhances its suitability for precise weighing and solution preparation in demanding laboratory protocols.
FAQs
1. What is the difference between Puratronic™ and standard reagent grade ammonium chloride?
Puratronic™ grade undergoes additional purification steps to achieve 99.999% metals basis purity, while standard reagent grade typically contains higher levels of trace metal impurities that may interfere with sensitive applications.
2. Can this product be used for preparing standard solutions in ICP-MS analysis?
The ultra-low trace metal content makes it highly suitable for preparing calibration standards and sample matrices in ICP-MS and other trace metal analysis techniques where background contamination must be minimized.
3. How should this material be stored to maintain its purity?
Store in a tightly sealed container in a cool, dry environment away from direct sunlight and sources of contamination. Use dedicated, clean spatulas to prevent cross-contamination during handling.
4. What documentation is provided with each batch?
Each package includes a certificate of analysis detailing the trace metal impurities profile, assay verification, and lot-specific information to ensure complete traceability and quality assurance.
5. Is this product compatible with standard laboratory glassware?
While compatible with most borosilicate glass, we recommend using dedicated high-purity containers for storage and preparation to prevent potential contamination from residual metals in standard glassware.
