Appendix B
Eluent Considerations
Caution: Always follow good laboratory practices when handling eluents. Know the
chemical and physical properties of the eluents. See the Material Safety Data Sheets for
the eluents in use.
This appendix describes eluents for use with your Waters 600E Multisolvent Delivery
System. It also provides information on eluent properties, including:
•
Eluent compatibility
•
Clean eluent
•
Eluent miscibility
•
Head height
•
Eluent viscosity
•
Eluent degassing
B.1 Eluent Compatibility with the 600E System
The Waters 600E System is constructed of high-quality, 316 stainless steel components
that, with some minor restrictions, can be used with all eluents.
This section lists the eluents that have, and have not, been approved for use with the 600E
System.
Eluents to Avoid
You can use any eluent with the 600E system. However, 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
System.
