Abstract: A detection device for detecting the presence of a substance of interest in a sample is described. The device can include a data store comprising executable instructions for at least one convolutional neural network, CNN, configured to process images: and a processor coupled to the data store and configured to execute the instructions to operate the at least one CNN. The detection device can be configured to: obtain spectrometry data, operate a first one of the CNNs to process the spectrometry data to obtain a first CNN output; apply a mask to the spectrometry data to obtain masked data; operate a second one of the CNNs to process the masked data to obtain a second CNN output; and determine if the substance of interest is present in the sample based on both the first CNN output and the second CNN output.

Abstract: An ion transfer tube assembly, a mass spectrometry system, and a method for providing an ion stream to an ion detection device are described that include using an ion transfer tube that provides a coaxial sheath gas flow. In an implementation, an ion transfer tube assembly includes an ion transfer tube for delivering the ion stream, where a sheath gas flows through the ion transfer tube, and where the ion transfer tube receives the ion stream from a first conduit coupled to an ion source; a pump fluidly coupled to the ion transfer tube, where the pump causes the sheath gas to flow through the ion transfer tube, where the ion stream is separated from the ion transfer tube walls by the coaxial sheath gas flow, and where the ion stream is received by a second conduit coupled to the ion detection device.

Abstract: Systems and techniques for optical spectrometer detection using, for example, IR spectroscopy components and Raman spectroscopy components are described. For instance, a system includes a first electromagnetic radiation source configured to illuminate a sample with a first portion of electromagnetic radiation in a first region of the electromagnetic spectrum (e.g., an IR source) and a second electromagnetic radiation source configured to illuminate a sample with a second portion of electromagnetic radiation in a second substantially monochromatic region of the electromagnetic spectrum (e.g., a laser source). The system also includes a detector module configured to detect a sample constituent of a sample by analyzing a characteristic of electromagnetic radiation reflected from the sample associated with the first electromagnetic radiation source and a characteristic of electromagnetic radiation reflected from the sample associated with the second electromagnetic radiation source.

Abstract: Described herein are a computed tomography scanning system for inspecting an object and methods incorporating the same. The system includes an imaging assembly including a frame positioned within an underground chamber below a ground surface, a platform coupled to and translatable with respect to the frame, and a stage coupled to and rotatable with respect to the platform. The platform is translatable to raise the object above the ground surface and lower the object below the ground surface when the object is on the stage. The imaging assembly also includes an X-ray source fixed with respect to the frame and configured to emit radiation that is attenuated by the object as the platform translates and the stage rotates, and an X-ray detector fixed with respect to the frame, the X-ray detector configured to detect the radiation transmitted through the object and generate a signal representative of the transmitted radiation.
