If you remove the safety shield before, the installation of the accessories is
easier to carry out. Proceed as follows:
1 Loosen the hexagon screws on the sides of the tower and remove
the safety shield.
2 Loosen the knurled screws on the rear of the tower and remove the
cable cover.
Do not forget to refasten the safety shields after the installation of the
accessories.
3.4 Mounting the needles
The length of the needle holder defines how deeply the piercing needle
penetrates the sample vessel.
If there is a danger that the heated sample could clog the needle, then
use the 6.2049.050 needle holder which is 73 mm in length. In this
case the piercing needle penetrates the sample vessel only slightly deeper
than the exhaust air needle and has no contact with the sample itself.
Caution
Movement with the needle holder 6.2049.050 may not extend more
deeply than up to Lift position 78 mm.
The 6.2049.040 needle holder, which is 58 mm in length, ensures that
the needle penetrates the liquid or powdery sample. The carrier gas can
flow through the sample and effect an efficient expulsion of the moisture
it contains. The 6.2049.040 needle holder can be ordered from Metrohm
if required.
