rates, all but eliminates this cross contamination concern by the
chromatographer. Teflon AF
®
has been used in certain optical systems
associated with HPLC for a few years without concern for normal HPLC
solvents. However, Teflon AF
®
is soluble in certain solvents (see page 16
Solvents/Mobile Phase) and must not be used to degas these types of
solvents.
Teflon AF
®
is permeable to some degree to water vapor whereas PTFE is
not. While the vacuum pump in the Vacuum Degasser contains internal
provisions for sweeping water or solvent vapor from the pump
continuously, it is possible that over time, high concentration buffers may
form crystals within the channel due to the loss of water within the
channel. The same precautions should be taken to prevent crystallization
within these channels as are taken for the HPLC pump. See the “Short-
term Shutdown” procedures.
