FAQs
1. What is the shelf life of this ammonium heptamolybdate reagent?
The reagent remains stable for at least 3 years from the date of manufacture when stored in its original, tightly sealed container under recommended conditions. Always check the label for the exact expiration date.
2. Can this reagent be used for preparing molybdenum blue solutions?
Yes, this ammonium heptamolybdate is suitable for preparing molybdenum blue solutions, which are commonly employed in spectrophotometric determinations of phosphates and silicates due to its high purity and consistent molybdenum content.
3. Is this product compatible with automated liquid handling systems?
The crystalline powder form dissolves completely in water, making it compatible with automated liquid handling systems once prepared as a solution. Ensure proper filtration if particulate-free solutions are required.
4. How should this reagent be stored to maintain its stability?
Store the reagent in a cool, dry place, away from direct sunlight and moisture. Keep the container tightly closed when not in use to prevent absorption of atmospheric moisture, which could alter its composition.
5. Are there any known incompatibilities with other laboratory chemicals?
Ammonium heptamolybdate may react with strong oxidizing agents or reducing agents. Avoid contact with alkaline solutions, as it may lead to precipitation or decomposition. Always refer to a compatibility chart before mixing with other reagents.
