Help how to test sn purity?

[sivvie]

So, I'm finally ordering sn, and on the listing it has a purity of over 98%. I'm just paranoid of it not being as pure as advertised because I really don't want to fail again at* ctb.

All the test kits i've found are for things like fish tanks, where the test requires you to take a sample of water from the fish tank, so I'm not sure that would work.

Is there any way to test its purity? Or, even if it's with the test kits made for fish tanks, I'd be willing to try it out.

Thanks for reading :)
