Capillary PEEK tubing offers
all the benefits of larger sized
PEEK tubing, whi le serving
as an excellent alternative to
more traditional fused silica and
stainless steel capillary tubing
(see Application Note below).
The capi l lary tubing can be
coupled to many of the products
in the Connectors chapter
(starting on page 34) and to some
of the valves in the Valves chapter
(starting on page 125).
High Pressure Tubing
FusedSilica Tubing
Five inner diameters with most common capillary outside
diameter, 360 µm
Cut in convenient lengths, up to 2 m
Theseproductsaremanufactured
from synthetic fused silica with a
polyimide coating.
An independent study conducted by a major pharmaceutical company
indicated LC-MS chromatographic performance could be improved in
some cases by switching the post-column transfer line from fused silica
to PEEK polymer tubing. The switch dramatically reduced peak tailing
and eliminated the degradation of peak symmetry as injection volume
was reduced. For more information, please contact us or order the
“Improved LC-MS Results Study” from the “Request Literature” section
of our website at www.idex-hs.com.
To straighten PEEK polymer tubing, frst choose a piece of stainless steel
tubing with an inner diameter slightly larger than the OD of your tubing and
with an appropriate length for the PEEK tubing you wish to straighten. For
instance, for 1/16” OD PEEK tubing with a length of 10”, choose our U-825
tubing (stainless steel, 1/8” OD x 0.08” ID x 25 cm long, page 69). Slip your
PEEK tubing into the stainless steel tubing. Place this “sleeved” tubing into
an oven and bake at 425 ºF (218 ºC) for 30 minutes or 350 ºF (177 ºC) for 60
minutes. Allow the sleeved tubing to return to room temperature naturally
(i.e., do not quench it with water). Once cooled, remove the PEEK tubing
from the stainless steel sleeve and inspect it for straightness. If needed,
repeat the process until the desired straightness is achieved.
Application Note
Because the thru-hole of our 25 µm ID PEEK tubing is very small, it is possible
for some fttings to cause the ID to become occluded. Please use caution,
especially with wrench-tightened fttings. For more information, please
contact IDEX Health & Science or your local distributor directly.
