WebMay 10, 2005 · The mean count rate (kcps) and z-average diameter (nm) of PNIPAM plotted as a function of temperature. The large increase in the mean count rate at a temperature of 32°C is consistent with previously published LCST values for PNIPAM. This increase in the scattered light results from a change in the refractive index of the … WebSize measurement of small molecules such as Vitamin B1 by dynamic light scattering (DLS) is a severe test of system performance. The Zetasizer Nano with NIBS technology is able to measure this molecule at concentrations below 50mg/mL H th rd Login Email address * Password * Login Forgotten password? Not registered yet?

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. WebMar 23, 2024 · The logarithm of the derived count rate (kcps) is plotted against the logarithm of the detergent concentration.

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.
