Because these ions contain more than one atom, they are called polyatomic ions. Click to enlarge. A prior knowledge of polyatomic interferences cited in the literature for a particular analyte mass may be helpful to the analyst for selecting Once an atom loses or gains electrons, the result is a beneficial or negative charge. Note: this list contains commonly-found oxidation states. most polyatomic interferences. CO3 2-carbonate C2O4 2-oxalate NO2 -nitrite NO3 -nitrate PO3 3-phosphite PO4 3-phosphate SO3 2-sulfite SO4 2-sulfate.
