i see, thx
would u mind to explain their differences? because my friend's father had been in the power plant business for quite sometimes, and the name "Ethylenediaminetetraacetic acid Tetraammonium Salt" is given by the father, because he's tired of his old provider and want my friend to help him find more. i would at least show him that I tried hard if I know more.
He has very efficient way to search for products, Im just doing this so I can impress him if u know what i mean.
thx
