Product Overview
Acetic acid, ammonium salt (98%+ purity) is a high-grade reagent specifically formulated for HPLC applications, ensuring minimal interference in chromatographic analyses. This crystalline powder exhibits exceptional solubility in water and polar organic solvents, making it a preferred choice for buffer systems in liquid chromatography. Its ultra-low impurity profile guarantees consistent baseline stability and peak resolution, critical for accurate quantitative and qualitative analysis. The compound’s neutral pH in solution (when properly buffered) prevents column degradation, extending the lifespan of HPLC equipment. Manufactured under stringent quality controls, this ammonium acetate variant meets international standards for analytical-grade chemicals, providing researchers with reliable, reproducible results. Its hygroscopic nature necessitates proper storage to maintain purity, while its compatibility with aqueous and organic mobile phases enhances versatility across diverse HPLC methodologies.
FAQs
1. What is the shelf life of this HPLC-grade ammonium acetate?
When stored in a tightly sealed container under cool, dry conditions, the product retains its specified purity for up to 24 months from the date of manufacture. Exposure to humidity may reduce its effective shelf life.
2. Can this ammonium acetate be used for LC-MS applications?
Yes, its high purity and low metal ion content make it suitable for LC-MS applications, though additional filtration (0.22 µm) is recommended to prevent particulate contamination in mass spectrometry systems.
3. How does this compare to ammonium acetate for general lab use?
This HPLC-grade variant undergoes additional purification steps to remove UV-absorbing impurities, heavy metals, and particulate matter, which are critical for chromatographic performance but unnecessary for routine lab applications.
4. What precautions should be taken during storage?
Store in an airtight container with desiccant packs to prevent moisture absorption. Avoid temperature fluctuations and keep away from direct sunlight to maintain chemical stability.
5. Is this product compatible with reverse-phase HPLC columns?
Yes, it is fully compatible with C18 and other reverse-phase columns when used within the recommended pH range (2.0–8.0). Always ensure the buffer pH is optimized for your specific column chemistry.
