Preparing the sample boats
¡
The sample boats may be contaminated. Temper the sample boats prior to analyz-
ing standard solutions and samples. Tempering is performed by an "empty measure-
ment".
¡
After tempering, do not touch the sample boat by hand any more. Store the boat in
a clean vessel, e.g., a petri dish. Transport the boat with a clean pair of tweezers.
¡
The sample material can have a blank value as well. The pharmaceutical industry
tests the effectiveness of cleaning processes with swabs. The swab can be tempered
on a boat before wiping. The blank value of the swab material can also be deter-
mined and taken into account.
¡
Fold the swab using a pair of tweezers until it can be placed on the boat. The swab
must only protrude slightly from the boat.
Performing the analysis
Only measurements with manual sample feed are possible with the integrated solids
module.
}
When creating a method for solids analysis, select the Horizontal Furnace option.
}
Click on [Start measurement]. Enter the sample ID and the sample type in the Mea-
surement start window.
}
Start the measurement with [Start].
}
Enter the sample amount in the Sample window. Exit the window with [OK].
}
After the prompt from the software, insert the sample boat in the furnace lock.
– Open the furnace lock.
– Insert the sample boat in the furnace lock. Hook the eye of the boat into the hook
on the feed (see image).
}
Exit the information window of the software with [OK].
}
Another information window opens. Follow the instructions and close the lock again.
}
Push the boat into the combustion furnace with the feed.

For multiple determinations: Start a second measurement with new sample material
by clicking [Start].
ü
At the end of the measurement, the results appear in the analysis report or in the
analysis table.
