Follow the recommendations for avoiding the growth of algae, see
Growth in HPLC Systems"
Small particles can permanently block capillaries and valves. Therefore,
always filter solvents through 0.22 µm filters.
Avoid or minimize the use of solvents that may corrode parts in the flow path.
Consider specifications for the pH range given for different materials such as
flow cells, valve materials etc. and recommendations in subsequent sections.
