Product Overview
Acetic acid, sodium salt (sodium acetate) in its 99% pure, anhydrous form is a high-performance reagent specifically designed for HPLC (High-Performance Liquid Chromatography) applications. This grade ensures minimal interference in analytical processes, making it ideal for sensitive chromatographic separations where purity and consistency are critical. The compound exhibits excellent solubility in water and polar solvents, allowing for seamless integration into mobile phase preparations and buffer systems. Its anhydrous nature eliminates moisture-related variability, ensuring reproducible results across experiments. The product undergoes rigorous quality control to meet strict HPLC-grade standards, with trace impurities kept below detectable thresholds. Its fine, free-flowing powder form facilitates precise weighing and dissolution, reducing preparation time in lab workflows. The chemical stability of sodium acetate makes it a reliable choice for long-term storage without degradation, provided it is kept in a tightly sealed container away from humidity.
FAQs
1. Is this sodium acetate suitable for LC-MS applications?
While primarily formulated for HPLC, this 99% pure anhydrous sodium acetate can be used in LC-MS applications, but we recommend verifying compatibility with your specific mass spectrometry conditions, as some residual ions may affect sensitivity in certain setups.
2. What is the typical shelf life of this product when stored properly?
The product maintains its specified purity for at least 24 months from the date of manufacture when stored in its original, unopened container at room temperature, protected from moisture and direct sunlight.
3. Can this be used as a substitute for sodium acetate trihydrate in buffer preparations?
Yes, but you will need to adjust the weight calculations to account for the absence of water molecules, as this is the anhydrous form. The molar concentration will differ from the trihydrate version.
4. What is the maximum recommended working concentration for HPLC mobile phases?
Typical working concentrations range between 5-50 mM, though optimal concentration depends on your specific separation requirements and the nature of your analytes. Always filter the solution before use.
5. Does this product contain any anti-caking agents or additives?
No, this is a pure anhydrous sodium acetate without any added anti-caking agents or flow aids, ensuring it meets strict HPLC-grade purity requirements for analytical applications.
