Cl and F measure in metallic powders

[PeterMetal]

Dear friends,

Some metallic powders have arrived to my hands,containing no-wished Cl, F, Na and K.

I would like to measure the quantity of these elements.

I have seen that the Argentometry is a good option for both Cl and F. Any other ideas?

This is not really my field, so I am like a Oktopus on a tree.

Thank you indeed for your time and help.

1. You can ask the supplier for a certificate of analysis
2. You can send a sample to an outside laboratory

If they are low levels a small sample of powder will be dissolved in acid and the solution is tested using ICP.
Not cheep or easy but very accurate and reliable.
