Abstract
An attempt to approximate the peak height determined by magnetic scanning from the intensity of ions detected on a photographic plate through the use of a mass spectrograph of the Mattauch-Herzog type has been empirically studied. The approximation has been performed by the use of calibration plots of logarithm of exposures against the reciprocal of the transmittance determined by a photodensitometer and by the use of a mass correcting factor . Thevalidity of the procedures was examined for the spectrum of choresterol which was measured according to a routine manner, giving an acceptable compromise between the two intensities.
