Solvent Recommendation for Agilent 1290 Infinity and 1290 Infinity II and 1260
Infinity II Flexible Pumps
Handling of Acids
Acids can corrode stainless steel and other materials in the flow path of LC
systems. For stainless steel, the minimum pH is 2.3 for corrosive acids and pH 1
for non-corrosive acids.
Please note that for non-volatile acids like phosphoric acid or perchloric acid
concentrations increase after evaporation of water. This means that originally
diluted acids can damage parts over time, e.g. because of liquid, which has left
the solvent path through micro leaks. Such systems should be flushed regularly
with pure water and may require shorter maintenance cycles. Using the seal
wash function should be considered for protecting pump heads.
