Connecting the sample tube
The sample uptake rate is governed by the internal diameter of the sample tube. Two
sample tubes with different internal diameters are provided with the autosampler. Each
sample tube has a screw connector on one end for connection to the sampling probe and
a screw connector on the other end for connection to the nebulizer via an adapter.
You use the sample tube with 0.6mm internal diameter (B300-0158) for routine samples.
You use the sample tube with 1mm internal diameter (B019-1060) if you are operating
the burner system with a High Performance Nebulizer; this sample tube allows the
nebulizer to attain its maximum performance.
To connect the sample tube to the sampling probe
Tower cover
.
Depending on how you position the autosampler with respect to the rest of the system,
you can attach the sample tube to either the front of the autosampler arm or the rear of
the tower cover. A spring clip with two slots is provided to hold the sample tube; the
narrower slot holds the 0.6 mm tube, while the wider slot holds the 1mm tube.
1. Screw the connector on the sample tube finger-tight into the fitting on
the sampling probe.
2. Make a smooth loop in the sample tube and then attach it to either the
front of the autosampler arm or the rear of the tower cover:
1. Insert the spring clip into the appropriate socket.
2. Thread the sample tube gently around the hook in the correct slot.
Note Do not kink or pinch the sample tube.

with two slots
Note The loop must be large enough so that the sampling probe holder can
move unhindered backward and forward along the autosampler arm.
