FAQs

1. What is the shelf life of HPLC-grade sodium acetate trihydrate?

The product remains stable for up to 24 months when stored in a cool, dry place in its original sealed packaging. Avoid exposure to moisture to prevent clumping or degradation.

2. Can this sodium acetate trihydrate be used for preparing mobile phases in HPLC?

Yes, it is specifically designed for HPLC applications, including mobile phase preparation, due to its high purity and low impurity profile, which prevents interference in chromatographic separations.

3. Is this product compatible with other common HPLC solvents like methanol or acetonitrile?

It is soluble in water and partially soluble in organic solvents. For mixed mobile phases, dissolve it in the aqueous component first before combining with organic solvents to ensure homogeneity.

4. Are there any alternatives to sodium acetate trihydrate for HPLC applications?

Alternatives include ammonium acetate or potassium phosphate buffers, but sodium acetate is often preferred for its buffering capacity in the pH range of 3.6–5.6 and compatibility with mass spectrometry.

5. How should this product be stored to maintain its purity?

Store in a tightly sealed container at room temperature, away from direct sunlight and moisture. Use desiccants if storing in humid environments to prevent hydration changes.
