3.1 Selection of Mobile Phase

3. OPERATION

● Explosion of vapor from flammable chemicals!
■ If a flammable chemical such as organic solvent
leaks from the flow path of the instrument and its
vapor concentration reaches the explosion limit, it
could cause spontaneous combustion with
dangerously explosive results.
When using a flammable and readily volatile
chemical, be sure to check for leakage from the
instrument flow path and ventilate the laboratory
room adequately.
NOTE: Restrictions on the use of mobile phase
depending on its characteristics and temperature
shall be followed carefully. (Refer to the table of
organic solvent characteristics in the instruction
manual of Chromaster 5110 pump.)
Particularly, solvents having a low boiling point
cannot be used because bubbles may be formed
in the degassing unit. Substances which may
solidify on the inside and cause precipitation
cannot be used either. When selecting a mobile
phase solvent, chemical resistance of the pump
and other flow path components should
adequately be taken into account.
