Figure 1.

Wavelength-resolved absorption spectrum (blue) of manganese (Mn, (left)) and molybdenum (Mo, (right)). The red line indicates the wavelength of manganese (λ = 279.4817 nm) and molybdenum (λ = 313.2594 nm), respectively. The measurement of the integrated signal over three pixels is indicated by the orange bar. The spectra shown were recorded during the quantification of the calibration standards of 6 μg L⁻¹ for manganese and 100 μg L⁻¹ for molybdenum.
