Maintaining the Instrument
•
Current Maintenance
— Replacement of reactors and adsorption filters and their filling materials.
For instrument configurations using special steel reactors for combustion it may be necessary also
to clean and remove the ashes from the crucible done with same material. See
.
•
Periodic Maintenance
— Replacement of the gas chromatographic column. The column lifetime
in EA IsoLink IRMS System for CNSOH instrument is evaluated in years. Replacement of the
seals of the reactors coupling unions placed on the furnace compartment base.
Current Maintenance Program
Each reactor, each filter and relevant fillings, need to be replaced according to the analytical
configuration used. Please refer to the
CookBook
for the best analytical setup for your samples.
Replacing Reactors and Adsorption Filters
The replacement of reactors and adsorption filters is performed after a preset number of analyses
according to the setting entered in the section
“Replacing the Filling Materials”
. Replace
and install reactors and filters.
