WebEn 1886, Eugen Goldstein observó rayos de descarga en gases a baja presión que viajaban lejos del ánodo y a través de canales en un cátodo perforado, opuestos a la dirección de los rayos catódicos cargados negativamente (que viajan desde el cátodo al ánodo). Goldstein llamó a estos rayos de ánodo con carga positiva Kanalstrahlen (rayos … WebFrancis William Aston won the 1922 Nobel Prize in Chemistry for his work in mass spectrometry In 1886, Eugen Goldstein observed rays in gas discharges under low pressure that travelled through the channels in a perforated cathode toward the anode, in the opposite direction to the negatively charged cathode rays.

History of Mass Spectrometry

In the mid-nineteenth century, Julius Plücker investigated the light emitted in discharge tubes (Crookes tubes) and the influence of magnetic fields on the glow. Later, in 1869, Johann Wilhelm Hittorf studied discharge tubes with energy rays extending from a negative electrode, the cathode. These rays produced a fluorescence when they hit a tube's glass walls, and when interrupted by a solid object they cast a shadow.
