Figure 3 demonstrates difference-mean linearity plots from a linear and a nonlinear flow cytometer. The correlation coefficients of Figure 3A and Figure 3B data were 0.95 and 0.73, respectively. The signal sat- WebLinearity is a related concept; if a detector’s output (in arbitrary units) is linearly proportional to the input light level, the detector is said to be linear. A perfect detector would have an infinite dynamic range and absolute linearity. Neither …

WebJan 11, 2024 · In DC operation, upper linearity is limited by how much current the PMT's voltage divider can supply to its dynodes. In pulsed operation, upper linearity is limited by space-charge effects (i.e., charge density of a preceding electron cloud repelling a succeeding one and hampering its progression) amongst the later dynode stages. WebPMT Linearity Measurement • DYB PMT linearity requirement: – Linearity is within ±2% for peak anode current from 0 to 40 mA. – Nonlinearity is less than 5% for peak anode current up to 60 mA.

WebMar 1, 1995 · For instance, speed of response, linearity, resistance to magnetic fields, and uniformity of response are all in part determined by the selection of the dynode (see Fig. 3). Response speed. Two basic properties—the design of the electron optics and the strength of the electric field between electrodes—determine the response speed of a PMT.
