Observe the following during analysis:
¡
To add samples of flammable substances in horizontal operation, always use ABD
with a flame sensor in automatic or automatic plus mode or an Autoinjector.
¡ To add samples of flammable substances, do not use the ABD in parameter mode,
or only use it with program parameters designed and tested for it (risk of soot!).
¡
Do not exceed the maximum permissible sample amounts (→ "Technical data for
the multi EA 5100 "
 172).
¡ Adjust the dosing rate to the sample matrix and observe the maximum dosing
speeds (→ "Technical data for the multi EA 5100 "
 172).
¡
Standard solutions with organic solvents can change composition rapidly due to the
volatility. Therefore, ensure that the clear space above the liquid in the sample cup
is small when preparing and storing samples. Store the solutions in the refrigerator.
The boiling points of the materials used should also not differ by more than 50 °C.
¡
Adjust the sample volume to the expected concentration to remain within the mea-
suring range of the detector.
¡ Begin the analysis with a standard solution and determine the daily factor. If the
value measured for the standard solution differs by more than 20 % from the target
value, repeat the measurement. If required, look for the source of the fault. If re-
quired, re-calibrate the analysis system.
