Solvent Information
Fused silica and Quartz (SiO
2
)
Fused silica is used in 1290 Infinity Flow Cells and capillaries. Quartz is used
for classical flow cell windows. It is inert against all common solvents and
acids except hydrofluoric acid and acidic solvents containing fluorides. It is
corroded by strong bases and should not be used above pH 12 at room
temperature. The corrosion of flow cell windows can negatively affect
measurement results. For a pH greater than 12, the use of flow cells with
sapphire windows is recommended.
Gold
Gold is inert to 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.
Zirconium Oxide (ZrO
2
)
Zirconium Oxide is inert to almost all common acids, bases and solvents.
There are no documented incompatibilities for HPLC applications.
Platinum/Iridium
Platinum/Iridium is inert to almost all common acids, bases and solvents.
There are no documented incompatibilities for HPLC applications.
Fluorinated polymers (PTFE, PFA, FEP, FFKM)
Fluorinated polymers like PTFE (polytetrafluorethen), PFA (perfluoroalkoxy)
and FEP (fluorinated ethylene propylene) are inert to almost all common
acids, bases and solvents. There are no documented incompatibilities for
HPLC applications. FFKM is perfluorinated rubber, which is also resistant to
most chemicals. As an elastomer, it may swell in some organic solvents like
halogenated hydrocarbons.
Sapphire, Ruby and Al

O
3
-based ceramics
Sapphire, ruby and ceramics based on aluminum oxide Al
2
O
3
are inert to
almost all common acids, bases and solvents. There are no documented
incompatibilities for HPLC applications.
