Page 6: Safety
The communication between the C-620 control unit and the SepacoreControl software is done via a serial RS232 cable (contained in the standard equipment). If the C-640 detector shall be used without the C-620 control unit, it can be connected directly to the C-660 fraction collector using the cinch cable. -

3 .5 .1 Deuterium lamp The primary light source of the detector C-640 is a deuterium lamp with an average lifespan of about 1000 operating hours. A lamp test can be performed across the whole range of the detectable spectrum (Scan) or on the four selected wavelengths of the detection channels (A–D) only. -
Page 16: Signals And Parameters
3 .6 .2 Range of wavelength The wavelength range of the detector C-640 depends on the assembly of the optical parts, the calibration results and the number of elements of the CCD sensor that are used at the same time for processing (“electronic half width of wavelength”) -
