5. PARTS REPLACEMENT
The following parts are consumables. Always prepare them for
replacement. Quantity of use is on a basis of rough standard,
assuming that the working days are 240 days a year, the working
hours are 8 hours a day. Normal life means usable time of the
part when the instrument is used with methanol flowing
(1.0 mL/min). However, since the values vary greatly depending
on the conditions (solvent, flow rate, pressure), prepare enough
quantity of each part, considering the actual conditions of use.
