Preparing the autosampler for the HydrEA technique
Prior to installing the HydrEA technique the graphite tube must be coated with iridium or gold
(see hydride system manual). Use the dosing tube used during graphite operation for this
purpose.
13. Switch off the AAS device and install the hydride system (e.g. HS 60 modular).
14. For the HydrEA technique remove the tube guide and dosing tube from the autosampler
arm of the AS-GF. Install the titan canula to the autosampler arm and attach it using the
lock screw.
15. Attach the reaction gas tube to the titan canula.

Adjusting the AS-GF
The AS-GF has already been installed according to Section "Installing the AS-GF" p. 44. The
fine alignment of the AS-GF to the furnace is supported by software. The autosampler is
aligned such that samples can be optimally deposited in the graphite tube.
