SGE Fused Silica Lined PEEKTM Tubing
P
EEKsilTM is polymer-sheathed fused silica tubing with an
effective outside diameter of 1/32", 1/16" and now
0.36mm. The sheathing polymer is polyether ether
ketone (PEEKTM) that is mechanically strong and has ideal
characteristics for sealing with conventional metal or polymer fer-
rule systems. PEEKsil may be used as a direct replacement for
conventional stainless steel as well as a replacement for PEEK
tubing used in liquid chromatography systems. The new 0.36mm
OD material allows it to be used directly in place of 0.36mm OD
fused silica tubing.
Advantage of PEEKsilTM
-
Robust Tubing -
The PEEK polymer exterior coating and the
fused silica combination makes PEEKsil very robust.
PEEKsil is therefore capable of withstanding high pressures,
making it ideal for capillary LC and LC/MS applications. All
PEEKsil tubing is pressure rated to 10,000psi.
-
Smooth Wall Surface -
The fused silica internal wall of
PEEKsil provides an exceptionally smooth surface, free of
imperfections, which ensures excellent flow characteristics.
Stainless steel, in contrast, has a very rough and pitted inner
wall surface,which has several detrimental effects on the
performance of a liquid chromatography system.
-
Solvent Compatibility -
PEEKsil is compatible with most
organic solvents. PEEKsil is resistant to strong acids and has
an effective pH range of 0 - 10. PEEKsil is not compatible
with hydrofluoric acid.
-
Inertness -
Fused silica is renowned for its extremely low
absorption characteristics and deactivated for critical
chromatography applications.
-
Precision of Inside Diameter -
The inside diameter of fused
silica tubing can be produced far more precisely and with a
greater range of sizes than is available with stainless steel.
-
Zero Metal Contact in LC -
The sample and mobile phase
do not come into contact with metal in PEEKsil tubing.
-
Ease of Connection -
PEEKsil is inherently straight, but is
very flexible, which makes connection between columns,
detectors and injectors easier than with more rigid stainless
steel tubing.
-
Applications of PEEKsil -
PEEKsil can be used in all
applications where solvents must be pumped under high or
low pressures with little flow resistance or possibility of
contamination. Typical uses are in LC connecting lines,
sample loops and sample lines.
