Accupik Accessory . 83
NOTE: The Accupik needs to be adjusted so that when the pan is punctured, the needle is close to
the middle of the sample pan in the crucible but slightly to the right of the crucible's handle.
There should be approximately 0.5 – 1 mm of space between the needle guide and the
crucible’s handle.
5.
Enter 1 in Select Carousel Location, then click the Piercing Position button.
The autosampler will rotate so that position 1 is underneath the Accupik needle.
6.
Loosen the black thumbscrew adjustment knob to carefully move the stem so that
the needle assembly (contains the needle tip) is slightly above the sample in the
crucible.
The space between the needle tip and the top of the sample tray should be
approximately 1 mm.
7.
Click the Piercing Depth button.
This moves the autosampler tray up and down to pierce the sample.
8.
Watch the position of the knob as the needle punctures the sample pan.
When the vertical direction or height of the needle is adjusted properly.
9.
Check the sample, if it is pierced (there is a hole) and the sample pan is not
deformed by the sleeve it is OK. If it is, the Accupik's height needs to be adjusted.
