Solvent Information
Introduction
Observe the following recommendations on the use of solvents.
• Follow recommendations for avoiding the growth of algae, see “Algae
Growth in HPLC Systems” on page 54.
• Small particles can permanently block capillaries and valves. Therefore,
always filter solvents through 0.4 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 like flow cells, valve materials etc. and recommendations in
subsequent sections.
