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.

MA: the resuspended sediment of GQD after low speed centrifugation (400 ×g); MNA: the resuspended sediment of GQD obtained by high speed centrifugation (15,000 ×g).
WebJan 18, 2024 · The derived count rate (kcps) is plotted against the polymer concentration (mg/cm 3) and reveals the concentration at which aggregation occurs. As presented in Fig. 2 , the Azo-HPG showed a low critical value with a CMC of 1.0 mg/cm 3 , indicating that the nanoparticles were easily self-assembled. WebMay 6, 2024 · Instead of measuring I par (d) directly, the backscatter time-averaged photon count rate I tot, which is an output of the size measurement autocorrelation process as the derived count rate (kcps), also contains residual background scattering which is light scattered by the medium which the particles are suspended in.
