Comments "A convenient pair of frequently used wavelengths in [researchers'] laboratory is 420 and 600 nm. The ratio of initial slopes of calibration curves or of the absorbance of very dilute suspensions is calculated in Table 2. The Cary and the Zeiss come quite close to the theoretical predictions."
