Solvent Information
Gold
Gold is inert against all common HPLC solvents, acids and bases within the
specified pH range. It can be corroded by complexing cyanides and
concentrated acids like aqua regia (a mixture of concentrated hydrochloric
and nitric acid).
Zirconium Oxide
Zirconium Oxide (ZrO
2
) is inert against almost all common acids, bases and
solvents. There are no documented incompatibilities for HPLC applications.
Platinum/Iridium
Platinum/Iridium is inert against almost all common acids, bases and solvents.
There are no documented incompatibilities for HPLC applications.
PTFE
PTFE (polytetrafluorethen) is inert against almost all common acids, bases
and solvents. There are no documented incompatibilities for HPLC
applications.
Sapphire, Ruby and Al

-based ceramics
Sapphire, Ruby and ceramics based on Al
2
O
3
are inert against almost all
common acids, bases and solvents. There are no documented incompatibilities
for HPLC applications.
Data above were collected from external resources and are meant as a
reference. Agilent cannot guarantee for the completeness and correctness of
such information. Information can also not be generalized due to catalytic
effects of impurities like metal ions, complexing agents, oxygen etc. Most data
available refers to room temperature (typically 20 – 25 °C, 68 – 77 °F). If
corrosion is possible it usually increases at higher temperatures. In case of
doubt, additional resources should be consulted.
