manual sample
introduction
With manual boat feeder (MBD)
automatic sample
introduction
With automatic boat feeder (ABD) for large sample series
combined with autosampler autoX 112 with AOX/solids rack
(column and batch method)
The multi-purpose combustion tube is used for AOX determination in horizontal
operating mode. The transformed hydrogen halides are quantified in the measuring
cell "sensitive".
Depending on the sample preparation, these samples may be quartz containers with
loaded activated carbon or filters with wet filter cake. The samples are inserted into a
quartz glass boats. The quartz glass boat is then introduced into the combustion tube
using the manual boat feeder (MBD) or the automatic boat feeder (ABD).
For large sample series it is possible to combine the ABD with the autosampler
autoX 112. Installation and commissioning of the ABD and the autoX 112 are
described in the respective devices' user manuals.
6.3.1
Preparing the analyzer (optional variant)
The preparation of the analyzer includes the following steps:
Installing the auto-protection assembly and the gas transfer line
Inserting the multi-purpose combustion tube
Prepare the chlorine module
CAUTION
There is a risk of burns on the combustion furnace! Only install the auto-protection
assembly when the device is cold or allow the device to cool down sufficiently!
NOTICE
Always switch off all components of the multi X 2500 before electrically connecting
them! Connecting or disconnecting electrical contacts may damage the sensitive
electronic components of the multi X 2500.
Installing the auto-
protection assembly
