Mounting the sample heating tube
Make sure that the O-ring is not damaged
when assembling the sample inlet.
Place the O-ring in the center of the sample
inlet retainer and pass the branch tube
through the sample inlet ring.
Do not confuse the head and tail of the ring.
Install the sample heating tube in the
retainer.
Insert the tube and tighten the screws.
(Tighten the 3 screws gradually in an
alternative manner until there is no
clearance.)
Install the Teflon joint and the mercury
collection tube to the sample heating tube.
Disassemble the Teflon joint, pass the
sample heating tube through the box nut,
washer, O-ring and joint in this order and
tighten the nut.
Here, do not insert the joint too deep so that
the position can be easily adjusted later.
* The thread on the Teflon joint is easily
damaged. Ensure to verify that the nut
turns smoothly. If the box nut does not
correctly engage the thread, it could result
in leaking.
Wipe the outside of the sample heating tube
and the mercury collection tube with alcohol.
