Title: Innovations of James Speakman
Introduction
James Speakman is a notable inventor based in Northwich, GB. He has made significant contributions to the field of mass spectrometry, holding a total of three patents. His work has advanced the technology used in analyzing samples through innovative designs and methodologies.
Latest Patents
One of his latest patents is a plasma mass spectrometer. This device comprises a plasma torch for generating ions from a sample introduced into a plasma. It features a nozzle-skimmer interface for transmitting ions into a first evacuated chamber, along with ion guiding means and an apertured diaphragm that divides the first evacuated chamber from a second evacuated chamber. The ion mass-to-charge ratio analyzer in the second chamber produces a mass spectrum. The ion guiding means includes a multipole rod-set, means for applying an AC voltage between rods in the set, and means for introducing an inert gas such as helium, neon, argon, krypton, xenon, or nitrogen into the ion guiding means. This design ensures that the partial pressure of the inert gas inside the rod-set is at least 10 torr, effectively reducing interfering peaks in the spectrum.
