To Use ProSteel Tubing

66
If you wish to use ProSteel tubing in place of fused silica in
the transfer line, the installation and removal procedures for
ProSteel tubing are similar to the fused silica procedures
except for the following steps:
Cut a ProSteel metal capillary (0.53 mm ID with
1
maximum OD of 0.67 mm) to approximately 1 m in length
using a precision tubing cutter.
2 If you intend to operate at temperatures 200 °C and
higher, you must use the ProSteel protective sleeve with
ProSteel tubing. Without the ProSteel protective sleeve,
the ProSteel tubing can permanently bind to the heated
conduit tube.
To install the ProSteel protective sleeve:
a Trim the ProSteel protective sleeve to match the length
of the transfer line (approximately 1 m), plus or minus
a few millimeters.
b Straighten the ProSteel tubing and protective sleeve.
c Slide the ProSteel tubing into the protective sleeve.
3 Follow the procedure for installing the fused silica into
the transfer line. See
into the Transfer
• Make sure the ProSteel protective sleeve protrudes a
few millimeters from both ends of the transfer line for
easy removal.
• Be sure to use the appropriate ferrule and nut
supplied with your ProSteel metal capillary.
See "To Remove the Fused Silica Column from the Transfer
Line" for removal instructions.
