Product Description

Compare the application

ATMP-Na5 is the pentasodium salt route for ATMP. The liquid reference gives27.8–30.7% as ATMP acid versus38–42% as ATMP-Na5 and1% solution pH10–11. This differs from ATMP-Na4 even where salt percentages look similar. Check neutralization state and receiving formulation rather than treating all sodium salts as near-neutral.

What should the trial compare?

Keep feed water, concentration factor, pH, temperature, oxidant exposure, mixing and residence time representative. Compare dissolved and deposited mineral, suspended material, filtration and operating trends. Verify metal corrosion and long-term membrane compatibility as separate endpoints when they are relevant to the application.
