6.13.3 Luminescence Detection
CAUTION
SWITCH ON THE INSTRUMENT AT LEAST 15 MINUTES BEFORE
STARTING A LUMINESCENCE MEASUREMENT. SOME COMPONENTS
NEED TO WARM UP TO GUARANTEE STABLE CONDITIONS FOR THE
MEASUREMENT.
The Infinite 200 PRO luminescence detection system utilizes the single photon
counting measurement technique. This is based on a dedicated luminescence
PMT with appropriate measurement circuitry. This technique is very robust
against noise. It is preferred for measurement of very low light levels.
For best performance it is recommended to use white plates for luminescence
measurements. For details see 5.9 Optimizing Luminescence Measurements.
Note
Results of luminescence measurements are always displayed
in counts per second (cps).
CAUTION
THE INSTRUMENT MUST BE PLACED IN A LOCATION AWAY FROM
DIRECT SUNLIGHT. ILLUMINATION > 500 LUX CAN NEGATIVELY
INFLUENCE LUMINESCENCE MEASUREMENTS.
