WebThe normalized derived count rate, which is related to the particle size and the concentration of particles, also increased, supporting the formation of larger particles. At N/P equal to – and higher than – 1.5, the normalized derived count rate of PEG-PGBA PICs was kept at comparable level ( Figure 2(c )), which indicates the formation of ... WebA graph of the count rate of the source against time is plotted. From the graph, the time taken for the count rate to fall by half is measured. A number of measurements are …
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 ...
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 = 10,000 photons / sec = 10 kcps . This … 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 … See more black and blue motorcycle jacketWebSep 19, 2024 · The derived count rate values for the 2:1 align with those for 2 mM FeCl 3 solution (no organics, used as a reference solution), and hence, no size data is shown for this ratio.
