HI96770 supplies the three powder components used to develop the color measured by a compatible photometer. On the HI97770, the method covers 0–200 mg\/L as SiO₂. That reporting basis matters: an elemental silicon result is not the same number as a silica result.

Add one packet of HI96770A-0 and dissolve it fully, then one packet of HI96770B-0 and dissolve again. Allow the specified 10-minute stage before adding one packet of HI96770C-0. After dissolving C, follow the final 2-minute countdown before reading.

Zeroing with the original sample addresses sample color and turbidity within the prescribed procedure, but does not remove every chemical interference.
