Latest Patents
One of Peter Arrowsmith's key patents is titled "Mass analyzer system with reduced drift." This invention involves a mass analyzer where an ion signal, typically from a plasma, travels through an orifice into a vacuum chamber. The signal then passes through a focusing system in the vacuum chamber into a mass spectrometer and ion detector. The design incorporates a small shadow stop placed in the vacuum chamber immediately behind the orifice, which greatly reduces drift of the detected ion signal. This innovation allows for improved detection of different elements by minimizing differences in drift. The focusing system includes a Bessel box lens, and further drift reduction is achieved by insulating the stop in the Bessel box lens from the barrel and biasing the Bessel stop differently from the barrel. Peter holds 1 patent for this groundbreaking technology.
