We report on the development of an optical setup based on a multipass optical cell and on Mid-IR frequency comb laser for breath analysis. The relevant spectrum covers many biomarkers described in [2]. Perilminary sensitivity estimation for Acetone, Ethane, and Pentane showed that we could reach about 500 ppbv, 10 ppbv, and 75 ppb respectively.
