C-640 Operation Manual, Version C
2 Safety
This chapter points out the safety concept of the instrument and contains general rules of behavior
and warnings from direct and indirect hazards concerning the use of the product.
For the users safety all safety instructions and the safety messages in the individual chapters shall
strictly be observed and followed. Therefore, the manual must always be available to all persons
performing the tasks described herein.
2 .1 User qualification
The instrument may only be used by laboratory personnel and other persons, who on account of
training and professional experience know the dangers, which can develop when operating the
instrument.
Untrained personnel or persons, who are currently being trained, require careful supervision by a
qualified person. The present Operation Manual serves as a basis for training.
2 .2 Proper use
The UV-VIS Detector C-640 has been designed and built as laboratory instrument.
It is able to detect and measure changes in the light absorption behavior of liquids passing through the
flow cell of the instrument. The absorption for four selected wavelengths is measured simultaneously
and scanning over the entire wavelength range of the detector (200 – 840 nm) becomes possible in
conjunction with the BUCHI SepacoreControl software and the control unit C-620.
A deuterium lamp acts as primary light source of the instrument, supported by a halogen lamp as
secondary light source. 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.
If the instrument is used with potentially toxic or hazardous substances, it has to be installed inside a
closed fume hood or glove box. In such case, the complete processing and system handling has to
be performed within the ventilated box to avoid toxication and other hazardous situations to the user
and the environment.
2 .3 Improper use
Applications not mentioned in section 2.2 are considered to be improper. Applications which do not
comply with the technical data (see section 3 of this manual) are also considered to be improper.
The operator bears the sole risk for any damages or hazards caused by improper use!
The following uses are expressly forbidden:
• Installation or use of the instrument in rooms, which require ex-protected instruments.
