Operating Instructions for the Spectronic 20-D Colorimeter Operating Instructions for the Spectronic 20-D Colorimeter by Ulrich de la Camp and Oliver Seely One of the most convenient, accurate and sensitive methods for measuring the concentrations of dilute solutions is by colorimetry or absorption spectrophotometry. The technique is based upon the measurement of the amount of light energy a solution absorbs from a beam of light of a certain wavelength. The wavelength chosen, is usually that one at which the absorbance, of the species to be analyzed, is at a maximum. The picture below is a representation of a Spectronic 20-D colorimeter which is the instrument you will be using in both the manganese and iron determinations.
