NOTICE
Chlorides and low pH can cause corrosion on stainless steel.
Rinse thoroughly with clean water after use.
Inspect the column regularly for signs of corrosive attacks,
which may cause column damage if untreated. Note that the
stainless steel bed supports are especially vulnerable to corro-
sion.
Chemical resistance chart
The following table presents a summary of information obtained from several published
sources, not from individual tests on column components. It should be used only as a
guide. The effect of chemicals will generally be more severe at higher temperatures.
Note also that the combined effects of agents have not been taken into account in this
table. The applicable chemical resistance depends on the configuration of the column
and the associated materials of construction.
WARNING
Some of the chemicals listed below may be flammable under cer-
tain conditions. Make sure to use the chemicals under conditions
where they are not flammable. Refer to local and/or national clas-
sifications of flammable liquids.
