Derived count rate kcps
WebDerived count rate (kcps) partially indicates the particle concentration. 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). WebBecause the derived count rate is proportional to cr6 (c is the particle concentration and r is the particle size), it can be used to detect nanoparticle formation or degradation.29,30 After 0.5 h of incubation, the count rate dramatically decreased by almost 1 order of magnitude (from 47041 ± 702 to 5383 ± 43 kcps), revealing the decrease in

Check the water by itself, filter the buffer, the count rate from the sample should be ~50 kcps, definitely below 100 kcps ...
Webfrom dynamic light scattering (DLS) is derived from a deconvolution of the measured intensity autocorrelation function of the sample. Generally, this is accomplished using a non-negatively constrained least squares (NNLS) fi tting algorithm, a common examples being CONTIN. Count Rate or Photon Count Rate WebOct 30, 2011 · Moreover the number of particles represented by the derived count rate is approximately twice as high for polyplexes of p(DAB–Bz) compared to polyplexes of …
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.
