4.
Apply a few drops of acetone to soften the rubber cement holding the ball to the
flared capillary tube.
WARNING:
Acetone is extremely flammable. It has a flash point of 0°F. It can
cause central nervous system depression. Harmful if swallowed. Causes irritation
to eyes, skin, and respiratory tract. Avoid eye and skin contact. Avoid ingestion
and inhalation. Refer to the Material Safely Data Sheet for further information.
AVERTISSEMENT:
L'acétone est extrêmement inflammable. Il a un point d'éclair
de 0°F. Il peut provoquer une dépression du système nerveux central. Nocif en
cas d'ingestion. Provoque une irritation des yeux, de la peau et des voies
respiratoires. Évitez le contact avec les yeux et la peau. Éviter l'ingestion et
l'inhalation. Reportez-vous à la fiche de données de sécurité pour plus
d'informations.
5.
Using of tweezers, grasp the short piece of platinum wire extending above the ball.
6.
Lift the ball off of the flared mount. If there is resistance, apply more acetone until
the ball is free.
CAUTION:
Do not apply excessive upward force! This may damage the balance.
ATTENTION:
Ne pas appliquer de force excessive vers le haut! Cela peut
endommager l'équilibre.
NOTE: If no platinum wire extends above the ball, a small piece of stiff wire (in the kit) may be
used to push up on the ball from the bottom end of the capillary tube.
7.
Once the ball is free from the capillary tube, clean off any residual rubber cement.
Use as many drops of acetone as needed. Acetone that remains trapped in the tube
may be "wicked" away with a tissue.
8.
Using tweezers, grasp the new replacement ribbon by the glass ball so that the loop
hangs downward.
9.
Carefully feed the loop end of the ribbon into the flared end of the capillary. Some
gentle flexing action on the ribbon may be necessary to get it to feed through the
tube. Be careful not to kink the ribbon.
NOTE: If the loop does not feed through the capillary tube properly, the platinum ribbon insertion
tool (P/N N5376741) may be used to pull the loop through the tube. Feed the hooked end of
the wire through the capillary tube from the bottom and capture the platinum ribbon loop.
Carefully pull the platinum ribbon through the capillary tube.
NOTE: This operation requires high dexterity with both hands. It is better accomplished with two
people.
10.
Suspend the proper tare weight from the loop in the new ribbon; go to step 15.
The following alignment steps are required ONLY when replacing the sample hangdown wire
side ribbon. (The tare weight ribbon may be fixed in any direction.)
11.
Install a hangdown wire and pan.
12.
Assess the position of the pan relative to the autosampler tray position. Decide in
which direction and by how much the ribbon loop needs to be rotated to achieve the
correct alignment.
13.
If some correction needs to be made, use tweezers to grasp the short piece of
