While the author has created permission to use his text here, I'm not sure that a straight copy-and-paste — which is what the largely appears to be — is suitable. It is too specific and technical for the subject, and does nothing to give a general read of what gas detectors actually are. The article needs a major rewrite.

Merge from Gas leak detection

Logically, gas leak detection is an application of the more general technology of gas detection and measurement. The two articles in question both have deficiencies, and neither has undergone heavy editing over time. Rather than splitting and duplicating content, it would be better to consolidate content into a single stronger article. Specifically, the more-detailed description of types of sensor can be imported into this article, which does not have strong coverage of the topic.

MOS Sensor

The current version states that "Metal–oxide–semiconductor (MOS) sensors were introduced in the 1990s. The earliest known MOS gas sensor was demonstrated by G. Sberveglieri, G. Faglia, S. Groppelli, P. Nelli and A. Camanzi in 1990. MOS sensors have since become important environmental gas detectors." I strongly believe that this cannot be correct. Metal oxide semiconductor sensors have been well established in the 1970s, when other uses for the "Taguchi Gas Detector" were already being explored (Z. GES. HYG. GRENZGEB; DTSCH.; DA. 1975; VOL. 21; NO 1; PP. 11-12). Additionally, I have paper copies from the early 1980s of instructions for building a breath alcohol tester from a amateur electronics magazine (ELO). From the US National Bureau of Standards, there is a paper from 1974 on the original use (gas leakage detection) of these sensors: https://www.govinfo.gov/content/pkg/GOVPUB-C13-c13ba01f36a6ebad22f1a49eb64fe1d5/pdf/GOVPUB-C13-c13ba01f36a6ebad22f1a49eb64fe1d5.pdf Figaro Inc. themselves state that they are in business with MOS sensors since 1968 https://www.figaro.co.jp/en/company/history.html Non-commercial sensors preceding Taguchi include http://dx.doi.org/10.1021/ac60191a001 (from 1962). Overall, the claim that Sbervelieri et al. invented this kind of sensor seems wrong in the light of these sources.

Instead, I would suggest to edit the paragraph to something like: "Metal oxide semiconductor (MOS) gas sensors were commercialized in the 1960s. One of the first providers was Figaro, Inc., funded by Naoyoshi Taguchi [1]. Therefore, the sensor type was referred to as Taguchi gas sensor in earlier publications [2], which soon explored use cases other than fire prevention [3]. MOS sensors have since become important environmental gas detectors." Wolfhard R (talk) 08:22, 14 April 2025 (UTC)[reply]

@Wolfhard R: Please edit according to your knowledge, citing publicly available sources. Wikipedia needs your input. Do not worry about format, other editors can fix that aspect. We really need experts.--Smokefoot (talk) 15:26, 14 April 2025 (UTC)[reply]

Merge proposal

Before doing something drastic, I am checking here. The article is a collection of technical factoids related to gases, anecdotes, and some fluff. It could probably redirect to Gas chromatography. What detecting a gas even mean? When Ullmann's Encyclopedia is searched, the first two chapters that come up are (a) Gas Production, 6. Analysis and Quality Control (which mainly emphasizes gas chromatography) and (b) Gas Chromatography. This articles was created with a weak concept, but good intentions. The initial article begins "Gas Detector General Information....For full compliance with the OSHA, standard governing confined spaces, 29 CFR 1910.146, it is necessary to rely on the expertise of safety and health professionals, such as industrial hygienists." --Smokefoot (talk) 16:10, 14 April 2025 (UTC)[reply]

Oppose. The gas detectors article has a bunch of technologies, but none seem to be the types used in GC detectors. Instead, it seems to talk mostly about leak detectors and other open-system types such as used for LEL and environmental sensing. DMacks (talk) 22:06, 3 May 2025 (UTC)[reply]
