For 10 points, name this law whose most wellknown formulation sets the absorbance equal to the product of the path length, concentration, and the molar extinction coefficient.
This law is the basis of devices which measure blood oxygen saturation in pulse oximetry. The absence of tryptophan, cysteine, and tyrosine can complicate the use of this law in determining the purity of OD280 protein samples. Deviations from it are caused by polychromatic radiation and changes in the analyte's index of refraction. This law relates the negative logarithm of the transmittance by the slope of a calibration curve to the concentration of the analyte. For 10 points, name this law whose most wellknown formulation sets the absorbance equal to the product of the path length, concentration, and the molar extinction coefficient.
This law is the basis of devices which measure blood oxygen saturation in pulse oximetry.
