12 Carefully angling the sample hang-down installation tool, lower the bottom into the furnace opening
until you have enough clearance to hold the tool and wire vertically without bending the wire (very
important).
Figure 26 Sample hang-down wire.
13 Insert the wire and sample hang-down installation tool vertically into the sample tube, being careful not
to bend the wire. Continue to raise it slowly, feeding it through the purge control cap until the top of the
wire protrudes from the opening in the cap.
14 Cover the furnace opening with a flat object that will completely block the opening.
15 Position the sample hang-down wire so that the double-bend hook is pointed to the left. Grasp the hang-
down wire with brass tweezers, being careful not to bend the wire.
16 Using tweezers, gently hang the double-bend hook (pointing to the left) on the hang-down loop. Maneuver
the hook until it is fully inserted through the loop.
