Water for HPLC is a high-grade reagent. Chemically, it is a polar inorganic compound which at room temperature is a tasteless and odorless liquid, with a hint of blue. It is a liquid between 0 c and 100 c. It has a variety of applications in chemical and biological sectors. This demineralized water is a universal solvent which is used to dissolve numerous chemical substances which is required in various Industrial sectors as well as for Agricultural, Pharmaceutical, Domestic, Laboratory and various other purposes. DM water is also commonly used for heat exchange, due to its availability and high heat capacity, for both cooling and heating. HPLC grade water minimizes contaminants such as ions, particles or bacteria which could pollute or destroy the pump/injector in equipment and affect separation quality. This reagent is suitable for the industrial synthesis of products and research applications. HPLC grade water is ultra-pure water with a low UV absorbance, which is often filtered through a 0.2-micrometre filter and packaged in a solventrinsed plastic
