Installing The Sample Tubing - PerkinElmer AVIO 500 Customer Hardware And Service Manual

Installing the Sample Tubing

To install the sample tubing refer to the instructions below and the next two figures:
1. Turn off the peristaltic pump using the software control.
2. Take a piece of 0.76 mm (0.030 in.) pump sample tubing. New pump tubing
will work better if it is pre-stretched, and analytical precision will be improved.
Grasp the tubing, with one clip in each hand, and stretch the tubing gently a
few times.
3. Install the pump tubing on an open channel of the pump. To do this, carefully
stretch the new tubing around the pump head and place the clips on the pump
tubing into the slots, using the slots in the same position on each side of the
pump head. Carefully thread the pump tubing through the lip of the cover (see
the next figure). Be careful not to twist or kink the pump tubing during this
process.
4. Take two pieces of 0.58 mm i.d. (0.023 in.) polyethylene tubing (Part No.
09908265), one for the sample capillary and one for the nebulizer capillary.
Using a razor blade, bevel one end of each piece of capillary tubing by cutting
it at an angle. See the next figure.
