Kurzfassung englisch:
Hydrogen sulfide (
H2S) trace gas detection
based on off-beam quartz-enhanced photoacoustic spectroscopy
using a continuous wave (CW), mode-hop-free
external cavity (EC) quantum cascade laser tunable from
1310 to 1210 cm−1 was performed. A 1σ minimum detection
limit of 492 parts per billion by volume (ppbv) using
a 1 s lock-in time constant was obtained by targeting the
line centered at 1234.58 cm−1. This value corresponds to a
normalized noise equivalent absorption coefficient for H2S
of 3.05 × 10−9 W cm−1 Hz−1/2.
