Solvent Information
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.
