The podcast “110 Histórias | 110 Objetos” (“110 Stories, 110 Objects”) covers the 110 years of history of Instituto Superior Técnico, through its past, present and future objects.

A collection of objects related to different fields, such as science, music, arts and sports, is the starting point for conversations with people who will tell us more about the history of these objects.

A new episode is released every week. The podcast “110 Histórias | 110 Objetos” (“110 Stories, 110 Objects”) is part of the Público newspaper podcasts.

Today’s episode (#30) – 21st January 2022: “110 Histórias | 110 Objetos” (“110 Stories, 110 Objects”) – The portable Gas Analyser.

Before the invention of electronic devices, simple daily tasks such as measuring chemical compounds in the air, required ostentatious devices that carried out physicochemical measurements. The portable gas analyser, also known as the Orsat apparatus, made these measurements possible in 1873. It is estimated that the model that belongs to the Técnico collection, has arrived at the time of the Chemical Engineering Laboratories’ creation.
It became a piece of laboratory equipment universally used, which allowed to compare measurements carried out in different laboratories, namely very important measurements such as the analysis of gases that factories release into the air, hazardous air quality in heavily polluted cities or indoor car parks, and also car exhaust smoke. Some of these measurements can save lives.
