We have also observed 1-5% decreases in the mean intensity of fluorescent
microspheres ("DNA-check" beads from Coulter) on our EPICS XL over
periods of 3-4 hours.

A question for EPICS XL users.
We see a consistant 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?
