Fitting and Connecting the Autosampler Sampling Probe
Fitting the Sampling Probe
1. If not already done, carefully insert the sampling probe guide from above into
the sampling probe holder on the autosampler arm and push it down fully, as
shown in the following figure.
2. Carefully insert the sampling probe from above into the probe guide.
3. Push the sampling probe down until about 20 mm protrudes from the bottom
end of the probe guide, then position the O-ring on the probe to set this
position, as shown in the following figure.
This is not the final position for the sampling probe. The probe can be adjusted
when the rinsing port has been set up. See the following procedure, Adjusting
the Sampling Probe Height on page 167 .
Note
The standard sampling probe is a PTFE-lined epoxy polymer tube. This
polymer is resistant to the acids, alkalis and organic solvents normally used
in atomic spectroscopy. If your samples contain an organic solvent that
attacks this polymer, a PTFE-lined stainless steel sampling probe is
offered as an option (Part No. B3000152).
