NaF analysis

[erolet]

I try to find instrumental analysis of NaF. Thanks

It would really help if you gave more details about what you are trying to do:

Solid NaF or in solution?

NaF itself, or impurities?

What is the matrix?

Thanks for your attention.
I titrate with 0,1 N perchloric acid for raw material...
I try to find in solution.
There are glycerin, EtOH, Nipagin M Na, sugar, sunset yellow, sodium saccarin.

Do you need to analyze fluoride or sodium? Sodium would be easiest using atomic absorption. Fluoride would be easiest using ion selective electrode. You could also use IC for either fluoride or sodium.

Why would you use AA, when you are set to do fluoride by ISE? Just use a sodium ISE with the same meter. You can calibrate with commercially available NaF ISE standards.

Looking at the sample matrix you could not infer the F content using Na analysis. There are other species containing Na.
