Gas Tracing uses an inert tracer gas, which is added to the mains pipe under pressure. A sensitive probe is used to detect where the tracer gas escaping through the ground, floor or wall. Thermal Imaging maps buried and hidden pipes and identifies abnormal heat patches. Moisture Meter maps any hidden damp caused by the leak.

2020-11-8A dual-frequency-comb spectrometer based on two quantum-cascade lasers is applied to kinetics studies of formaldehyde (HCHO) in a shock tube. Multispectral absorption measurements are carried out in a broad spectral range of 1740–1790 cm–1 at temperatures of 800–1500 K and pressures of 2–3 bar. The formation of HCHO from thermal decomposition of 1,3,5-trioxane (C3H6O3, 0.9% …

Gas chromatography-selected ion monitoring (GC-SIM) is often used for the quantification of GAs by GC-MS, an internal standard labeled with stable isotopes (usually with deuterium) being used as the most reliable and sensitive method. A mass chromatogram reconstructed from full-scan GC-MS is also used for semiquantification.

2020-12-18RHB series infrared carbon dioxide alarm detector is used in concentration detection of carbon dioxide and concentration excess alarm. It adopts international advanced NDIR non-dispersed gas analysis technique, CO2 measurement can not be interfered by other gases, it is simple to operate and convenient for carry.

A gas sensing method based on quartz-tuning-fork enhanced photothermal spectroscopy (QEPTS) is reported in this paper. Unlike usually used thermally sensitive elements, a sharply resonant quartz-tuning-fork with the capability of enhanced mechanical resonance was used to amplify the photothermal signal level. Acetylene (C2H2) detection was used to verify the QEPTS sensor performance.
