shows a linear correlation between
the integrated absorbance signal and the sample mass in the range
from 0.5 to 3.0 mg. Each measurement point in Fig. 2 corresponds
to an individual sample weighing and measurement, as it is almost
impossible and also unnecessary to weigh and introduce repeatedly
the same sample mass. Wheat flour masses >3 mg, however,
required a longer pyrolysis time in order to be pyrolyzed efficiently;
this approach has not been investigated systematically, as the volume
capacity of the solid sampling platform also reached its limits,
resulting in difficulties of sample transfer to the graphite furnace.
