Derived count rate 意味
If an attenuator is used during the measurement that allows only 0.3% of the light to pass then the measured mean count rate will only be 0.3% of the signal one would be obtaining if no attenuator were present. In the Zetasizer a range of different attenuators can be used, and in automatic mode the system will … See more If the detector in the Zetasizer collects 1,000,000 photons over the duration of 100 seconds, then the mean count rate during that measurement was 1,000,000 photons / 100 sec = … See more In principle, in a perfect sample the derived count rate could be used for static light scattering (SLS), where the scattering as a function of sample concentration leads to the … See more Select a workspace, for example the size workspace, and then edit it – Record View Parameters – Measurement – Size – Derived Count Rate and move it to the work space with the right arrow.
