To display the derived count rate in your software, check the FAQ mentioned in ‘ How to display a custom parameter’. Example 1: if the sample has a mean count rate of 200 kcps, and the Zetasizer used an attenuator of 0.3% attenuation then the derived count rate woulld be 100 kcps / 0.3% = 100 kcps / 0.003 = … 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 = 10,000 photons / sec = 10 kcps . This … See more 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 … 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.
