WebThe blue peaks show the results of data acquired at low flow rate. The red peaks show data acquired at high flow rate. At high flow rate, the peaks broaden and shift, both of which compromise the quality of the data. 2. Check PMT linearity. Another important component of acquiring cell cycle data is that the detectors, the PMTs, need to be linear. WebNonetheless, in flow cytometry, instrument linearity can still be demonstrated. The ICSH/ICCS guidelines propose the use of beads to demonstrate instrument linearity using voltage settings applied to a …
