**5. LmPy-GC/MSMS system performance**

The analyses of both types of samples showed in the chapter it was possibly observed that apart from the variation of laser parameters no significant difference, referent to the relative abundance of the hydrocarbon products, was observed between analyses of the same sample. Nevertheless, it was observed that parameters such as; the size of the formed craters and thus the intensity of the pyrolyzate distribution are degree focusing dependent as well as span time, and laser's energy settings (**Figure 15**).
