Product Overview
Ammonium iron(II) sulfate hydrate, Puratronic™ grade, delivers ultra-high purity (99.999% metals basis) for demanding laboratory applications where trace metal contamination must be minimized. This crystalline powder is meticulously processed to ensure consistent composition, making it ideal for analytical chemistry, spectroscopy, and other high-sensitivity techniques. The hydrated form provides stability while maintaining solubility in aqueous solutions. Its low impurity profile—with metals reduced to parts-per-million levels—ensures reliable results in quantitative analyses. The compound’s stoichiometric iron content and ammonium coordination enhance its utility in redox reactions and complexometric titrations. Packaged under inert conditions to prevent oxidation, this reagent is supplied in airtight containers to preserve its integrity. Whether used as a primary standard or in trace element studies, its Puratronic™ certification guarantees reproducibility across experiments. The material’s fine particle size ensures rapid dissolution, reducing preparation time for critical procedures.
FAQs
1. What is the difference between Puratronic™ and standard-grade ammonium iron(II) sulfate?
Puratronic™ grade undergoes additional purification steps to achieve 99.999% metals basis purity, reducing trace contaminants like lead, copper, and zinc that could interfere with sensitive analyses. Standard grades typically contain higher impurity levels.
2. Can this compound be used for preparing iron standard solutions?
Yes, its high purity and precise iron content make it suitable for preparing primary standard solutions in volumetric analysis, provided proper dissolution and dilution protocols are followed.
3. How should this product be stored to maintain its purity?
Store in a tightly sealed container under dry, inert conditions (e.g., nitrogen atmosphere) at room temperature. Avoid exposure to air or moisture to prevent oxidation and hydrolysis.
4. Is this compatible with common laboratory solvents like ethanol or acetone?
It is primarily soluble in water. Solubility in organic solvents like ethanol or acetone is limited; pre-testing is recommended for specific applications.
5. What alternatives exist for applications requiring lower purity?
Reagent-grade or ACS-grade ammonium iron(II) sulfate (typically 98-99% purity) can be used for general laboratory purposes where ultra-low trace metals are not critical.
