Method: Fractional distillation of liquid air
The discovery of neon relied on the technique of fractional distillation of liquid air, a complex and meticulous process that allowed Ramsay and Travers to separate and identify the individual components of this frigid mixture.
The process began with the liquefaction of air, achieved by subjecting it to extremely low temperatures and high pressures. Once the air was in its liquid state, it was introduced into a specialized distillation apparatus. This apparatus consisted of a series of chambers, each maintained at a slightly different temperature.
As the liquid air passed through these chambers, its components began to separate based on their different boiling points. The gases with lower boiling points, such as nitrogen, evaporated first and were collected in separate containers. Neon, with a relatively high boiling point, remained in the liquid phase.
By carefully controlling the temperature and pressure within the distillation apparatus, Ramsay and Travers were able to isolate neon from the other components of liquid air. This process required patience, precision, and a deep understanding of the physical properties of gases.
The successful application of fractional distillation to liquid air opened up new avenues for the study of gases and paved the way for the discovery of other noble gases. It also demonstrated the power of physical methods for separating and analyzing complex mixtures, a technique that continues to be essential in various fields of science and industry.
