Patent number: 10859556Abstract: Systems and methods for analyzing an unknown sample are disclosed. The system includes at least one subsystem to obtain molecular information about the sample and at least one other subsystem to obtain elemental information about the sample. The system also includes a data collection component to collect and combine the information from the subsystems to create combined analytical information and a multivariate model that relates known attributes to information previously generated with at least two analytical systems that are the same types of systems as the at least two analytical subsystems. A prediction engine applies the multivariate model to the combined analytical information to produce predictions of attributes in the unknown sample.Type: GrantFiled: October 9, 2018Date of Patent: December 8, 2020Assignee: Malvern PANalytical Inc.Inventors: Daniel A. Shiley, Brian Curtiss
