3.2 Principle of operation
Extending the multi EA 5000 / multi EA 5100 or the multi X 2500 by the ABD sampler
module allows determination of the sulfur, nitrogen, chlorine and carbon content partic-
ularly in solids, but also in liquids and gases. The ABD can only be used in horizontal op-
erating mode.
Solids are weighed into quartz boats and transferred into the sample sluice. Liquids are
metered onto the quartz boat through the injection port at the sluice flap. The sample is
supplied either manually or automatically using the Multi Matrix Sampler or autoX 112
Multi Matrix sampler.
The quartz boat is moved out of the cooled sluice into the combustion tube with the aid
of a quartz glass hook. The boats are transported according to the program chosen in
the multiWin control and analysis software.
The ABD can be operated in three different modes:
parameter, automatic, automatic plus
Parameter mode The boats are transported, according to the parameters chosen in multiWin, without
flame sensor control. The following parameters can be configured:
¡ Hold points (max. 3)
¡ Waiting times (max. 3)
¡
Feed speeds before and between hold points (max. 3)
A program that has been created can be saved and combined with methods (of the
same aggregate condition) in the multiWin control and analysis software.
Automatic mode The combustion is controlled fully-automatically via the evaluation of the flame sensor.
This mode is universal and can be used for liquid and solid samples, varying sample ma-
trices and varying sample quantities.
Automatic plus mode The combustion is controlled fully-automatically via the evaluation of the flame sensor.
Via a test drive of the ABD, a time-optimized combustion takes place. This is adjusted to
the specific sample matrix and the selected sample quantity. A program that has been
created must be saved and combined with a method (of the same aggregate condition)
before it can be used.
For metering of gaseous samples, a flexible cannula including screw cap and septum is
placed onto the sluice port of the ABD. The cannula is connected with the gas metering
module. The ABD is merely the connecting link between the gas metering module and
the combustion system. Mechanical feeding or control of combustion via the flame sen-
sor does not take place in this case. The sample sluice is not cooled.
