Consult: 1% sodium selenite

I would like to ask: 1% of sodium selenite in polyminerals refers to 1% se content? Or does it mean 1% sodium selenite-- it should mean selenium-- thank you, Xiaoli. What is the use of 1% sodium selenite? Immunity, sodium selenite, potassium iodide, cobalt chloride-personally, technical quality control personnel must understand this kind of basic knowledge, especially when designing formulations. -how much do you use in the full price of sodium sulfite? At the end of this post, 1% sodium selenite was edited by crude protein at 21:07 on 2009-11-23. Sodium selenite generally refers to the purity of sodium selenite raw material, the real selenium content = 1%*Se/Na2SeO3 about 0.46%, but sometimes it is marked on the package: Se:1.0% refers to the selenium content at this time! -- Thank you very much for the explanation of crude protein, which is very clear-- the addition of selenium should be accurate and it is easy to go wrong.
