Jim -- I tried to make this easy for people to calculate their instrument deadtime with a simple experiment anyone can do and then to use this number to see from queueing theory graphs what losses they will see on their instruments due to deadtimes. The main article, which has been very popular, is my "Strategies for Rare Cell Detection and Isolation" (chapter 20) in Methods in Cell Biology vol. 42. Some of this material is also in the unit on High Speed Cell Sorting I wrote for the newest edition of Current Protocols in Cytometry. Best regards, Jim Leary On Monday, October 20, 1997 Jim Weaver wrote: There have been previous discussions that I am unable to locate in the archives about the maximal rate that the cytometer can perform analysis without missing cells due to electronics dead time. I specifically need this information for an older model Coulter Elite if possible although any data will be appreciated. Thanks for your help. James F.
