Abstract: A method and system for identifying a Raman spectrum component of an observed spectrum is provided. The observed spectrum is produced by interrogating a material such as a tissue sample with light at the one or more predetermined wavelengths, and the observed spectrum includes a background fluorescence component representative of fluorescent emissions resulting from the light interrogation and a Raman spectrum component representative of a Raman scattering resulting from the light interrogation. The method includes a) creating a reconstructed fluorescence spectrum representative of the background fluorescence component of the observed spectrum using one or more empirically determined fluorescent spectral profiles; and b) identifying the Raman spectrum of the observed spectrum using the reconstructed fluorescence spectrum.

Abstract: A multi-dispersive spectrometer is provided in which the spectrometer comprises an optical system configured to direct an excitation signal from an excitation light source toward a sample, receive a spectroscopy signal from the sample, and direct the spectroscopy signal toward the detector. The optical system comprises a movable optical component adapted to move the spectroscopy signal relative to at least one sensor of the detector and the detector is adapted to detect a plurality of discrete shifted spectroscopy signals. A method of obtaining a Raman spectrum from a sample is also provided. The method comprises directing an excitation signal from an excitation light source toward a sample; receiving a spectroscopy signal from the sample; and directing the spectroscopy signal toward a detector, wherein the spectroscopy signal is moved relative to at least one sensor of the detector to provide a plurality of discrete shifted spectroscopy signals.

Abstract: Systems and methods for characterizing biological specimens, which may involve identifying a cell type or state corresponding to a disease or health condition of a subject. A biological specimen is subjected to electromagnetic radiation for spectroscopic analysis such as Surface Enhanced Raman Spectroscopy (SERS) to determine the relative abundance of proteins or amino acids in the cells, which is used in a comparison to previously stored relative abundance data of a database to automatically identifies at least one of cell type and/or cell state of the cells (or the disease/health state of the subject with the disease state including the possibility of virus infection, or drug susceptibility of a subject to bacteria or fungus). The method may also be employed with biological entities or cellular structures such as exosomes and even protein or nucleic acid fragments to determine disease states or health states of the subject.

Abstract: Devices and systems for analyzing biological samples are provided. Devices include a hollow body extending from a first end to a second end. The body defines a sample collecting portion. A first opening at the first end of the body is operable to receive a source of negative pressure and a second opening at the second end of the body is operable to receive a biological sample. The body also includes an optically transparent region disposed in a region corresponding to the sample collecting portion, the optically transparent region being configured to transmit electromagnetic radiation therethrough from an imaging device capable of imaging the biological sample when disposed in the sample collecting portion.

Abstract: A Brillouin modality can be supplemented by an auxiliary modality, such as an optical imaging modality or a spectroscopy modality. In some embodiments, the auxiliary modality can be used to guide the Brillouin measurement to a desired region of interest, so that acquisition times for the Brillouin measurement can be reduced as compared to interrogating the entire sample. The auxiliary modality may have an acquisition speed faster than that of the Brillouin modality. In some embodiment, the auxiliary modality determines a composition of materials within a voxel in the sample interrogated by the Brillouin modality. Using the information provided by the auxiliary modality, the Brillouin signatures corresponding to the materials within the voxel can be unmixed, thereby providing a more accurate measurement of the sample.

Abstract: In one embodiment, a pipeline interchange flows a product through an upstream pipeline. An automated analyzer is connected to the upstream pipeline to analyze different physical and/or chemically properties in the product and generate data from the product without extracting a sample from the upstream pipeline. An automatic splitter is placed downstream of the automated analyzer, capable of receiving and interpreting the data from the automated analyzer and directing the refined petroleum product into at least three different downstream pipelines, wherein at least one of the downstream pipelines is a transmix pipeline.

Abstract: In one embodiment, a process is taught where the process begins by flowing a first product through a first pipeline and flowing a second product through a second pipeline. In this embodiment, the first product in the first pipeline is analyzed with a first product automated analyzer that is capable of physical and/or chemically analyzing the first product in the first pipeline and generating a first product data. Additionally, in this embodiment, the second product in the second pipeline is analyzed with a second product automated analyzer that is capable of physical and/or chemically analyzing the second product in the second pipeline and generating a second product data. The process then produces a blended product by mixing both the first product and the second product within a pipeline interchange which is connected downstream to both the first pipeline and the second pipeline. The blended product then flows from the pipeline interchange to a third pipeline that is connected downstream of pipeline interchange. The first product data and the second product data is then interpreted in a data analyzer by comparing the physical and/or chemical characteristics of the physical and/or chemical characteristics of the first data to an optimal first data and the physical and/or chemical characteristics of the second data to an optimal second data. The data analyzer then determines the adjustments in the flow of the first product and the flow of the second product to achieve optimal blended data from the blended product. The adjustments are then communicated to adjust the flow of the first product in the first pipeline and the flow of the second product in the second pipeline.
