Derived count rate
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 WebJan 9, 2024 · Rate = Number of R waves (rhythm strip) X 6; The number of complexes (count R waves) on the rhythm strip gives the average rate over a ten-second period. …

WebDerived rates require an active Advanced Rates add-on! The derived rates allow for more flexible prices based on your standard rates. Derived rates calculate their prices by adding or subtracting amounts (Derived Amount rate) or percentage (Derived Percent Rate) to/from an existing standard rate. When the prices in a standard rate change, the ...
