Top 5 Things You May Not Know About Mass Spectrometry

1. The instrument that many consider the first mass spectrometer was called a “parabola spectrograph” and was constructed in 1921 by J.J. Thompson, the renowned British physicist who had some years earlier discovered the electron.

2. It was during the 1940s that MS began to move away from its academic origins to find use in more practical applications such as nuclear isotope enrichment and the study of the composition of petroleum.

3. In 1941, John Hipple designed the first portable mass spectrometer which was marketed by Westinghouse Electric. However, this model did not seem to catch the imagination of scientists, and was not a commercial success.

4. In 1946, the first time-of-flight (TOF) mass analyzer was developed by W. Stephens of Pennsylvania. TOF MS involves acceleration of ions through an electric field of known strength, which confers the same kinetic energy to all ions of equal charge. By measuring the time taken for a particle to reach the detector, the mass/charge ratio of particles can be calculated.

5. In 1948, the first mass spectrometer to use electron ionization (EI), the MS-2, was launched by Vickers in Manchester, England. Also that year, the first ion cyclotron mass spectrometer, known as the Omegatron, was developed at the University of Minnesota.
