This product is not an ammonium standard, but a nitrogen standard (in the form of ammonium). If written, 'NH4+ standard as N', that would imply that the product is an ammonium standard, which this is not; it is an ammonium *nitrogen* standard.

The way this is named is super confusing. Normally, I would see NH4+ standard written "as N" meaning that only the nitrogen is considered toward the concentration. This seems to indicate that the NH4+ molecular weight is used to calculate the conc!?!
