Figure 26 – Sample Capillary Tubing
Feed the sample capillary tubing from the rear of the nebuliser through the upper holder in
the cover and towards the pump.
Ensure there are no twists or bends that may prevent flow of the sample.
Pass the drain capillary tubing through the lower holder in the cover and towards the pump.
This holder contains a sensor detecting bubbles produced when the spray chamber is
draining normally. The plasma and the pump will be switched off after 2 minutes if no bubbles
are detected.
Figure 27 – Pump Tubing
Release the pump tubing clamps and locate the sample and drain pump tubing over the
pump rollers, locking the lugs on the pump tubing into the left and right clamps.
Connect the sample pump tubing to the sample capillary tubing and the drain pump tubing to
the drain capillary tubing; remember to allow for the direction of flow.
Pump tubing should be inspected before each analysis and be replaced if there are
indications of wear.
Additional lengths of capillary tubing should be used to allow connection to the input of the
sample pump tubing to the sample and the output of the drain pump tubing to a waste
container.
Figure 28 – Pump Tension Adjustment
The pump tension can be adjusted with the plasma running and the pump stopped. Lock the
