Frequently asked questions
What is HPLC-grade water used for?
HPLC-grade water is primarily used as a mobile phase solvent in high-performance liquid chromatography (HPLC) to ensure accurate, reproducible analytical results.
What is the chemical formula and molecular weight of HPLC-grade water?
The chemical formula is **H₂O** with a molecular weight of **18.02 g/mol**.
How should HPLC-grade water be stored?
Store at ambient temperature in a tightly sealed container to prevent contamination, ideally in a clean, dry environment.
What grade of water is this, and how does it differ from other grades?
This is **HPLC-grade water**, which meets stringent purity requirements (typically ≤5 ppb TOC) for chromatographic applications, far exceeding laboratory or reagent-grade standards.
Can Molekula supply HPLC-grade water in bulk?
Yes, we offer HPLC-grade water in bulk quantities—please contact our sales team for custom packaging and delivery options.
What documentation comes with an order of HPLC-grade water?
Each order includes a **Certificate of Analysis (CoA)** detailing purity metrics (e.g., TOC, conductivity, microbial limits) and a **Safety Data Sheet (SDS)**.
