Abstract : Quantitative interference microscopy is an established method for determining dry mass in cells and cell components. Conversion of analogue values of phase retardation to absolute values in grams requires knowledge of a proportionality factor. Experiments elucidated the variabilities of this factor in respect to a number of preparation techniques. Instrumental errors were assessed.
