Product Overview
Citric acid monohydrate (HPLC grade) is a high-purity, crystalline powder designed for precise analytical applications. Its consistent composition ensures reliable results in chromatography, where even minor impurities can compromise accuracy. This grade is highly soluble in water, forming stable solutions that maintain pH integrity over extended periods. The monohydrate form provides enhanced stability during storage and handling, making it a preferred choice for laboratories requiring reproducibility. Its low heavy metal content and minimal organic impurities align with stringent HPLC standards, ensuring compatibility with sensitive detectors. The compound’s chelating properties further contribute to its utility in buffer systems, where metal ion interference must be minimized. Each batch undergoes rigorous testing to confirm compliance with HPLC-grade specifications, guaranteeing performance in demanding analytical workflows.
FAQs
1. What is the difference between HPLC-grade and reagent-grade citric acid?
HPLC-grade citric acid undergoes stricter purification to eliminate trace impurities that could interfere with chromatography, while reagent-grade may contain higher levels of contaminants suitable only for general lab use.
2. Can this product be used for preparing mobile phases in HPLC?
Yes, its high purity and low UV absorbance make it ideal for mobile phase preparation, ensuring baseline stability and accurate peak resolution.
3. How should this citric acid be stored to maintain its purity?
Store in a tightly sealed container at room temperature, away from moisture and direct sunlight, to prevent hydration changes or degradation.
4. Is this citric acid compatible with mass spectrometry (MS) applications?
While primarily designed for HPLC, its low impurity profile also makes it suitable for LC-MS applications where volatility and ion suppression must be minimized.
5. Are there any known incompatibilities with common HPLC solvents?
It is fully compatible with water, methanol, and acetonitrile but may precipitate in highly nonpolar solvents like hexane.
