WebNov 8, 2024 · The maximum count rate for the measurement should be 500-600 kcps. The attenuator will need to be adjusted after measuring the scattering intensity on maximum intensity in most cases, especially if the count rate is greater than 600 kcps. 2) Dilution check: The second way to verify that the concentration is suitable for DLS measurements … Webtime interval, constitutes the count rate. One may count again for the same amount of time and find a slightly different number of counts with a slightly different count rate. Here we see an example of a directly measured physical quantity (the counts) and a derived physical quantity (the count rate). The question which arises is what is the ... 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.

WebIf the above function is estimated for many measured intervals with various values of D subtracted (and for various values of n) it should be found that for values of D above a certain threshold, the above equation will be nearly true, and the count rate derived from these modified intervals will be equal to the true count rate. Time-To-Count ... WebThe "derived count rate" is a calculated parameter in the Zetasizer Nano software, and is representative of the scattering intensity that would be measured at the APD in the absence of the laser attenuation filter. The APD detector in the Zetasizer Nano exhibits a linear response across a broad range of light intensity.
