“…In sensor test set-ups, several mass flow meters are most often used. The set-ups are prepared for the use of several gases in a shift [ 20 , 72 , 73 , 74 , 75 ]. This is a better solution (measurement errors were limited) than using one gas line and one flow meter with simultaneous cylinder replacement or switching [ 76 ], although this is much more expensive.…”

“…In 2019, Barauskas et al [ 90 ] performed an in situ experiment in which some of the measurements characterizing the properties of the gas-sensitive material were performed simultaneously with the measurement of sensor properties, and the rest of the research was carried out in a separate experiment [ 90 ]. Further examples of in situ experiments are presented in [ 20 , 64 , 70 , 74 , 79 , 115 , 116 ]. Measurement operando is the real-time and operating characteristics of the active sensor element with simultaneous measurement of sensor properties and monitoring of the gas composition surrounding the sensor.…”

Measurements of the properties of gas-sensitive materials are a subject of constant research, including continuous developments and improvements of measurement methods and, consequently, measurement set-ups. Preparation of the test set-up is a key aspect of research, and it has a significant impact on the tested sensor. This paper aims to review the current state of the art in the field of gas-sensing measurement and provide overall conclusions of how the different set-ups impact the obtained results.

“…At room temperature, a pure SnO 2 sensor presented a negligible response even for 100 ppm NH 3 [ 95 ]. However, the graphene–SnO 2 hybrid sensor yielded a response of 21% for 50 ppm NH 3 , with response/recovery times of 15/30 s and without the interference of VOCs [ 96 ].…”

Since the first graphene gas sensor has been reported, functionalized graphene gas sensors have already attracted a lot of research interest due to their potential for high sensitivity, great selectivity, and fast detection of various gases. In this paper, we summarize the recent development and progression of functionalized graphene sensors for ammonia (NH3) detection at room temperature. We review graphene gas sensors functionalized by different materials, including metallic nanoparticles, metal oxides, organic molecules, and conducting polymers. The various sensing mechanism of functionalized graphene gas sensors are explained and compared. Meanwhile, some existing challenges that may hinder the sensor mass production are discussed and several related solutions are proposed. Possible opportunities and perspective applications of the graphene NH3 sensors are also presented.

A simple, cost‐effective, and novel chemical sensor for ammonia (NH3) gas detection was developed from polyaniline (PANI)/quail eggshell (QES) composites. QES is a natural waste enriched in calcium carbonate. In this work, pure PANI was synthesized from chemical oxidation method and PANI/QES composites were prepared from physical mixing of QES with the synthesized PANI at different mass ratio. A series of complementary techniques including Fourier transform infrared and ultraviolet‐visible spectrometers, scanning electron microscope with energy dispersive detection coupled with mapping, thermogravimetric analysis, and X‐ray diffractometer were used to characterize the physicochemical and textural properties of the biocomposites. From the results, PANI/QES composite with a mass ratio of 1 exhibited the lowest NH3 detection limit of 5.24 ppm with a linear correlation coefficient (R2) of close to unity (0.9932) between the signal and NH3 gas concentration. As a whole, the PANI/QES biocomposites synthesized from this work exhibited excellent selectivity toward NH3 gas even in the presence of other gas impurities, such as acetone, ethanol, and hexane. For the sensor reusability, the PANI/QES biocomposites can be reused in the application of NH3 gas detection for at least 4 cycles.
