Solvent Information
significantly reduces corrosion rates. Titanium is sensitive to acidic metal
chlorides like FeCl
methanol, which can be avoided by adding a small amount of water (about
3 %). Slight corrosion is possible with ammonia > 10 %.
Diamond-Like Carbon (DLC)
Diamond-Like Carbon is inert to almost all common acids, bases and solvents.
There are no documented incompatibilities for HPLC applications.
Fused silica and Quartz (SiO
Fused silica is used in Max Light Cartridges. 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
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.
