Determination of carbon monoxide using a coated quartz ...

· Carbon monoxide was detected and determined by a piezoelectric quartz crystal sensorcoated with nickel(II)-phthalocyanine 50 % (v/v) solution in glycerine. Studies on the effect oftemperature, flow rate, and some possible interferents were carried out. Calibration curves, sensorstability (lifetime) and the precision of measurements were also verified.

Compact and sensitive mid-infrared all-fiber quartz ...

based sensor for carbon monoxide (CO) detection was demonstrated by using a mid-infrared all-fiber structure as well as a 3D-printed acoustic detection module. An all-fiber configuration has advantages of easier optical alignment, lower insertion loss, improvement in system stability, reduction in sensor size and lower cost. The 3D-printed acoustic detection module was introduced to match the ...

[PDF] Ultra-sensitive carbon monoxide detection by using ...

A quartz-enhanced photoacoustic spectroscopy (QEPAS) based sensor for carbon monoxide detection at ppbv levels was developed with a μm external-cavity quantum cascade laser operating both in continuous wave (cw) and pulsed modes. A 23-fold enhancement of the measured CO signal amplitude was obtained when water vapor, acting as a catalyst for vibrational energy transfer, was added to the ...

Ultra-high sensitive light-induced thermoelastic ...

An ultra-high sensitive light-induced thermoelastic spectroscopy (LITES) sensor based on a resonant high Q-factor quartz turning fork (QTF) and a Herriot multipass cell was demonstrated for the first time, to the best of our knowledge. The performance of LITES and widely used tunable diode laser absorption spectroscopy (TDLAS) were experimentally investigated and compared at the same ...

Parts-per-billion detection of carbon monoxide: A ...

· In this work, we developed a QCL-based sensor for trace gas detection of carbon monoxide, using two interchangeable modules for detection of the optical absorption. Pressure waves have been detected by means of a QEPAS spectrophone, composed by a custom quartz tuning fork with a resonance frequency of f 0 ∼ kHz and mR tubes having a length of mm and an internal …
