I Love to Laugh Mr. Wigg, is said to float because of an excess of "laughing gas", although it is clear that the term is not used in the chemical sense. So-called "laughing gas" (nitrous oxide) was one of the earliest effective anaesthetics developed in the Nineteenth century. it was popularised by dentists, for pain-free tooth extractions, as well as by showground novelty booths. Customers at the booth would be gassed and, as they were recovering from the drugged sleep they often felt euphoric and giggly. Hence the name. A famous 1931 British comedy sketch starring Cicely Courtneidge, called "Laughing Gas", was based on
Gas chromatography who was awarded the Nobel Prize for his work in developing liquid–liquid (1941) and paper (1944) chromatography, laid the foundation for the development of gas chromatography and he later produced liquid-gas chromatography (1950). A gas chromatograph is a chemical analysis instrument for separating chemicals in a complex sample. A gas chromatograph uses a flow-through narrow tube known as the "column", through which different chemical constituents of a sample pass in a gas stream (carrier gas, "mobile phase") at different rates depending on their various chemical and physical properties and their interaction with a specific column filling, called the "stationary phase".
