3.29.1 98BToo long combustion of a very low carbon sample
Fig. 24: Programm screenshot (graph example 1)
It appears like a long tailing at the end of the peak. It appears in the low carbon
range only and the distance to the base line is in the range of 10 to 50mV.
Depending on the blanks of the crucibles and on the oxygen purity, the level of the
tailing can be as high as 100mV. When the burning is extremely long, the level of
the low carbon tailing even starts to grow.
Possible solutions:
- Reduce the analysis time
- Increase the comparator level of the low carbon range,
- Reduce the generator time.
