Choice of Rotor Seal
Vespel
™
Seal (for standard and micro valves only)
The standard seal has sealing material made of Vespel. Vespel is suitable for
applications using mobile phases within the pH range of 2.3 to 9.5, which is
suitable for the majority of applications. However, for applications using
mobile phases with pH below 2.3 or above 9.5, the Vespel seal may degrade
faster, leading to reduced seal lifetime.
Tefzel
™
Seal (for standard valve only)
For mobile phases with pH below 2.3 or above 9.5, or for conditions where
the lifetime of the Vespel seal is drastically reduced, a seal made of Tefzel is
available (see “Injection-Valve Assembly” on page 168). Tefzel is more
resistant than Vespel to extremes of pH, however, is a slightly
softer
material.
Under normal conditions, the expected lifetime of the Tefzel seal is shorter
than the Vespel seal, however, Tefzel may have the longer lifetime under
more extreme mobile phase conditions.
PEEK Seal (for preparative injection valve only)
The preparative injection valve has a sealing material made of PEEK. This
material has high chemical resistance and versatility. It is suitable for
application using mobile phases within a pH between 1 and 14.
N O T E
Strong oxidizing acids such as concentrated nitric and sulfuric acids are not
compatible with PEEK.
