FIA signals obtained using the electrolyte solution as carrier stream, consisting of 0.1 mol L⁻¹ K₂SO₄ and 5.0 × 0⁻⁴ mol L⁻¹ FeSO₄·7H₂O. The concentrations evaluated were: (a) 5.0 × 10⁻⁵ mol L⁻¹ (b) 5.0 × 10⁻⁴ mol L⁻¹ (c) 1.0 × 10⁻³ mol L⁻¹; (d) 1.0 × 10⁻² mol L⁻¹ (e) 2.5 × 10⁻² mol L⁻¹ and (f) 5.0 × 10⁻² mol L⁻¹.
