  • Method of monitoring the preparation of a photographic emulsion by conductivity measurements
    Patent number: 5272027
    Abstract: While preparing a photographic emulsion a conductivity reading is continuously or periodically taken from the batch during creation. The conductivity of the batch is compared to a standard plot of conductivity versus time representing an ideal batch preparation process. When conductivity of the batch deviates from the standard plot by more than a pre-determined level, an operator can discard the batch, compensate for the deviations, identify the cause of the deviation for use in correcting existing processes and procedures or optimizing future procedures, or compensate for the deviations.
