We see a conistant 5-7% decrease in the mean intensity of fluorescent
microspheres measured by our EPICS XL over a period of 3 hours from morning
start up. Ambient room temperature varies less than 2 degrees. Coulter is
not sure if this exceeds any of their specifications for performance.
My question is if this is a systemic problem. Do any other XL users see
similar behavior?
Thanks
