Where it appears
NT Labs says lanthanum binds phosphate and forms a solid that can be removed by the filter.
What cannot be inferred
A dissolved phosphate reading does not show the amount of suspended or retained material. Do not infer a lanthanum chloride label or compare bottle strength from an element name alone.
What to capture
Record the exact product, how the sample was obtained, and the filter in use. Leave the chemical form blank unless the manufacturer actually gives it.
