    XD 7500 Operation Kinetics The Kinetics function allows the temporal tracing of the absorbance and transmission of a sample with a particular wavelength. The photometer automatically calculates the slope between two adjacent measuring points from the available measurement data. If necessary, the catalytic activity can also be determined and displayed. To record the kinetics, the photometer carries out single measurements at regular time intervals (measurement intervals) and saves the measurement values as a function of the time.
