Solvent Recommendation for Agilent 1290 Infinity and 1290 Infinity II and 1260
Infinity II Flexible Pumps
Seals for Normal Phase Applications
For running normal phase applications on Agilent Infinity and Infinity II pumps,
yellow PE seals are required as piston seals. By default, 1290 Infinity, 1290
Infinity II, and 1260 Infinity II Flexible Pumps use ceramic pistons and yellow PE
seals as piston seals. 1260 Infinity I/II pumps use sapphire pistons and black
PTFE piston seals in a standard configuration. If using black PTFE seals with
normal phase applications, the black PTFE seals wear and generate small
particles. Such particles can clog valves and other parts in the flow path. When
running normal phase applications on 1260 Infinity I/II pumps, the piston seals
have to be changed to yellow PE seals. For optimum performance, PE seals
should be replaced during preventive maintenance.

CAUTION
Corrosion of valves
Normal phase balls/valves corrode quickly in aqueous solutions and acids (at
or below pH 7).
 Do not use normal phase valves in applications running with aqueous
solutions.
