Product Overview
Ammonium acetate HPLC is a high-purity, crystalline salt designed for demanding laboratory applications where precision and consistency are critical. This reagent-grade compound is meticulously purified to meet HPLC (High-Performance Liquid Chromatography) standards, ensuring minimal interference in analytical procedures. Its excellent solubility in water and polar solvents makes it ideal for buffer preparation, mobile phase modification, and protein precipitation protocols. The product undergoes rigorous quality control to eliminate trace metals, organic impurities, and particulate matter, guaranteeing reliable performance in sensitive assays. With a neutral pH in solution, it maintains sample integrity during chromatographic separations. The anhydrous form provides stability during storage, while its low UV absorbance at common detection wavelengths prevents signal interference. This versatile reagent is particularly valued in mass spectrometry-compatible workflows due to its volatility, which allows for easy removal during sample preparation. The 1 kg packaging offers cost-effective bulk supply for frequent users while maintaining the product’s purity through airtight sealing.
FAQs
1. What is the typical solubility of this ammonium acetate in water?
This HPLC-grade ammonium acetate exhibits high solubility in water, typically dissolving at concentrations exceeding 100 g/100 mL at room temperature, forming clear, colorless solutions suitable for most lab applications.
2. How does this compare to regular laboratory-grade ammonium acetate?
The HPLC grade undergoes additional purification steps to remove UV-absorbing impurities, heavy metals, and particulate matter that could interfere with chromatographic separations or mass spectrometry analysis, unlike standard laboratory grades.
3. What storage conditions are recommended for maintaining product quality?
Store the unopened container in a cool, dry place away from direct sunlight and moisture. After opening, keep the container tightly sealed to prevent hydration from atmospheric moisture, which could affect the product’s performance.
4. Is this product compatible with LC-MS applications?
Yes, this ammonium acetate is specifically suitable for LC-MS applications due to its high purity and volatility, which prevents residue buildup in the mass spectrometer and minimizes ion suppression effects during analysis.
5. What alternatives exist for buffer preparation if this product is unavailable?
For similar applications, ammonium formate or ammonium bicarbonate can serve as alternatives, though their pH profiles and volatility characteristics differ, which may require protocol adjustments for optimal performance.
