The Pyrola pyrolyzers can heat a sample so fast and so efficiently that a sample, for example a laminate, can be pyrolyzed slice by slice; the pyrolysis equivalent of a microtome.

The method is called pyrotomy, and the sample is exposed to several extremely short thermal pulses (in order of milliseconds). Then only the part of the sample that is in direct contact with the platinum filament will be heated in each pulse, giving a separate pyrolysis for each layer of the sample. Then if the sample consists of for example a coated paper or a laminate, the pyrograms will give information of each layer separately, instead of having all of them mixed in a single pyrogram.
