SN purity really that important?

[Relic]

The last test was with 1,25g of SN in 500ml water and then 1ml of that into another 500ml glass of water.
The color was darker when it was dry.

Should be good enough then. Might not be 99%, only a lab could verify that, but still fairly high nitrite level.

Is there a simple way to seperate the NaNO2 from the NaNO3?

There are different ways to prepare NaNO2 from NaNO3, but the process is not that simple.

Now after an hour it dried. Now it is exactly at 5 mg/L

Sounds very good to me. I know we're dealing with an extremely important topic here and I understand your concern, but considering your results I would stop worrying if I were you

Lets say it's not good and I will use it anyways, but survive, will I get permanent damage? Have you heard of people who just woke up again and had permanent damage?

Ok I noticed the plastic bag is useless.

The general consensus here is a failed attempt with SN doesn't seem to lead to permament damage. Many user reported failing with it for various reasons - the most common being calling for help or being found by someone - and none of them (or almost none of them) reported permanent damage.
