A Brief History of Mass Spectrometry Jennifer Grifﬁths A few of the great people and major discoveries that have shaped this century-old technique. As the applications of MS rapidly expand, so does the number of mass spectrometrists. For example, in , the American Society From Positive Rays to Proteins.1 “When he was forced to Cited by: The analysis of positive rays is based on the determination of the ratio of the charge to the mass of various constituents. The corre- sponding measurement for the negative corpuscle has however been carried to a much greater degree of accuracy by means of methods in- volving the magnetic deflection of the rays through large angles, and the refocusing of rays which make slightly .
Secondary-ion mass spectrometry (SIMS) is a technique used to analyze the composition of solid surfaces and thin films by sputtering the surface of the specimen with a focused primary ion beam and collecting and analyzing ejected secondary ions. The mass/charge ratios of these secondary ions are measured with a mass spectrometer to determine the elemental, isotopic, or molecular composition of Related: Fast atom bombardment, Microprobe. A common unit of electric current is the ampere, which is defined as a flow of one coulomb of charge per second, or × 10 18 electrons per second. The centimetre–gram–second units of current is the electrostatic unit of charge (esu) per second. One ampere equals 3 × 10 9 esu per second.. Commercial power lines make available about amps to a typical home; a watt .

Anode Rays → Rays of Positive Electricity and Their Application to Chemical Analyses — Retrograde and Anode Rays Joseph John Thomson The rays we have hitherto been considering consist of positively charged particles travelling in the direction in which such particles would be moved by the electric field in the discharge tube.
An anode ray is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed in Crookes tubes during experiments by the German scientist Eugen Goldstein, in Later work on anode rays by Wilhelm Wien and J.
