700XA after LSIV (A) has been removedFigure 4-13:
Replacing LSIV seals
Due to the possible damage caused by the presence of solids in the sample stream,
combined with the regular, repeated motion of the injection valve stem, LSIV seals may
require annual replacement.
Note
Specific application conditions should dictate the frequency of the seals replacement and you should
monitor analytical performance to determine appropriate replacement intervals.
Note
ID numbers listed in parenthesis refer to “LSIV - Exploded View” in Figure 4-14.
1. Halt sample flow and allow time for the LSIV to cool.
2. Remove the actuation portion (ID No. 26) of the valve by unscrewing the union
coupling (ID No. 19) from the heater section (ID No. 11), which should remain
attached to the GC. A union coupling wrench has been provided for this purpose.
