Has anyone seen an answer to the question of:
What impact does having the shipped vial sit in the tube for 3 to 4 days (more or less since I dont know the shipping method) have on the chemical make up of the water sample?
I ask because I know that there could be some changes at the chemical and elemental level that comes along with temperature variations or just how long something sits. From my experience working in a chem lab analyzing tylenol, we could see the structural changes in a carbon element occur within seconds!
+1 about "temperature" some ppl pay $ 200 test for drinking water, ship on cooler.
