Series 200 Operating Precautions
To protect yourself from harm and to prevent malfunctioning of the system, please observe
the following guidelines when operating the UV/VIS Detector:
• Before using the instrument, pay attention to the warnings presented in the beginning of
the manual.
• Wear the appropriate protective clothing, including safety glasses and gloves, when pre-
paring samples and solutions for use with this instrument.
• Always follow the correct safety procedure and the manufacturer's recommendations
when using solvents.
• Keep solvents with a boiling point less than 30
°
C under helium (10 kPa) in an optional
solvent cabinet (for example, the SEC 4).
• Do not keep buffer solutions in the system when the instrument is not in use, since salt
may crystallize out.
• Do not use acidic chlorides with pH less than 7; they can cause corrosion. Chloroform and
tetrachloromethane decompose slowly and form HCl.
• Do not use chloride TRIZMA buffers since they form HCl in equilibrium. Use phosphate
buffers instead.
• Do not use inorganic acids, concentrated organic acids or acidic buffer solutions.
• Ensure that the system is flushed with degassed solvent.
• Ensure that the other instruments in the system are ready to run.
• Ensure that all connecting communications and power cables are correctly installed for
your analysis.
• It is possible to clean the exterior surfaces of the instrument with a soft cloth dampened
with a mild detergent and water solution. Do not use abrasive cleaners or solvents.
