Attaching Sample And Drain Tubing - Thermo Scientific iCAP 6000 Series Maintenance Manual

iCAP Customer Training Manual
After assembly of the sample introduction system and prior to ignition of the plasma a
check should be made for correct assembly :-
Make sure the torch is fully rotated and locked in place.
Make sure the centre tube holder is fully rotated and locked into the torch.
Make sure the spray chamber connector is fully pushed into the torch body.
Make sure the spray chamber is tightly connected to ball the joint.
Problems in any of these areas may cause air leaks or disruption of the gas flows making
the plasma difficult to ignite and may cause damage to the torch.

2.3 Attaching sample and drain tubing

Figure 13 – 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 in the nebuliser and drain PTFE tubing that may
prevent flow of the sample. Insert the sample and drain PTFE tubing into their respective
Tygon pump tubing, making sure that the drain tubing is threaded through the lower hole in
the case (see Figure 14 below) for the drain sensor to work correctly.
Please note: the drain tubing should be connected correctly to account for the counter-
clockwise flow.
