Latest Patents

Ristroph's latest patents include innovative designs such as pulsed ion guides for mass spectrometers and related methods. This invention involves an ion guide that generates a radio frequency (RF) field to radially confine ions to an ion beam along a guide axis. The RF field's effective potential includes an alternating series of barriers and wells, allowing ions to be trapped in individual wells in a mass-dependent order. Larger masses are trapped closer to the guide exit than smaller masses, and the RF field can be scanned to release ions in the same mass-dependent order. This technology ensures that ions across the entire mass range arrive at a desired downstream focal point simultaneously, which is particularly useful in time-of-flight analyzers.

Another significant patent by Ristroph is related to time-of-flight mass spectrometry using multi-channel detectors. This invention utilizes a multi-channel ion detector to detect ions traveling in separate flight paths, which are spatially dispersed along a drift axis and/or a transverse axis within a flight tube of a TOF analyzer. The ion beams can be dispersed by various factors, including drift energy and ion mass, allowing for enhanced analysis capabilities.
