System Description and General Operation
Figure 5 Stainless steel tank
All the optional vessels are fitted with float switch, which trigger an audible
alarm should the eluent container run too low or the waste container get too
full. No action by the instrument will take place at this point and, therefore, it
is advisable to check the levels in the solvent vessels daily and to set the
minimum pressure slightly above zero, so that if the pump is starved of
solvent, the low minimum pressure alarm will be activated and cause the
system to default to the STANDBY mode.
