Why does the QIAxcel System or QIAxcel Advanced need to be calibrated?

The QIAxcel System or QIAxcel Advanced works on the basis of fluorescence detection technology. Each channel has a separate excitation light source, with its own optical detection. So each gel cartridge channel is different in the fluorescence emission signal collection mode with its own background and/or baseline noise. When you use a new cartridge, calibration (intensity normalization) is necessary to equalize the variations.
