From: Photoacoustic gas monitoring for anesthetic gas pollution measurements and its cross-sensitivity to alcoholic disinfectants

Fig. 3

The gas monitor with filters for isoflurane (a), desflurane (b), or sevoflurane (c) mistakenly detects anesthetic gases, although alcohols and alcoholic disinfectants (ad) were used (n = 5 per interfering agent). The strength of the cross-sensitivity was highest for isopropyl alcohol (alc.). d shows the increase of the actual sevoflurane concentration (black line) by interfering agents
