Solvents To Avoid; Solvents To Use - Waters Alliance e2695 Operator's Manual

This section lists the solvents that have and have not been approved for
use with the separations module.

Solvents to avoid

The following solvents attack or dissolve the Teflon AF tubing in the in-line
vacuum degasser:
• All perfluorosolvents produced by 3M under the trade name
Fluorinert™
• All perfluorosolvents produced by Ausimont under the trade names
Galden™ and Fomblin™
Caution:
perfluorosolvents is immediate and irreversible.
Long-term static exposure to halide salts (for example, fluoride, bromide,
chloride, and iodide) will cause pitting and corrosion of stainless steel parts.
When using these salts, flush your system thoroughly with water if the pump
will be idle for more than two days. See

Solvents to use

Materials of construction used in the separations module are nonreactive with
most acids, bases, salts, and organic solvents.
The solvents listed in the following four tables have been approved for use
with the separations module. These include salts, acids and bases in
concentrations up to 1 M (unless otherwise noted), and organic solvents in
concentrations of up to 100% (unless otherwise noted). Higher concentrations
can be used in many instances.
Information on the use of a specific solvent or concentration that is not listed
in this manual can be obtained by contacting Waters.
