Abstract: The present invention relates to methods of detecting parasites, viruses, bacteria and drugs in human and animal blood and cerebral spinal fluid (CSF), using laser-induced breakdown spectroscopy (LIBS). The method includes developing and using algorithmic detection models for detecting compounds, bacteria, viruses and parasites in blood or CSF. The models are developed from a sample of blood or fluid, knowingly having one or more of the compounds or bacteria, viruses, or parasites. Spectra are generated by a LIBS instrument from the sample, and are grouped into either classification spectra or verification spectra. Algorithmic models are developed from the classification spectra; these models are verified with the verification spectra. A second sample of different blood or CSF may then be assessed using the algorithmic models. Spectra generated from this second sample are applied to the models to determine the presence or absence of compounds or bacteria, viruses and parasites of interest.

Abstract: A method for monitoring of siloxane compounds in a biogas includes the step of generating a first absorption spectrum based on a ratio of a first spectral measurement and a second spectral measurement. The first spectral measurement is from a non-absorptive gas having substantially no infrared absorptions in a specified wavelength range of interest and the second spectral measurement is from a sample gas comprising the biogas. The method also includes the step of calculating a concentration of at least one siloxane compound in the biogas using a second absorption spectrum based on, at least, a first individual absorption spectrum for a known concentration of the at least one siloxane compound.

Abstract: The present subject matter relates to an apparatus and related method of high-speed analysis of product samples during production of the product. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward optical detectors. Signals from the optical detectors are compared to determine characteristics of the product under analysis. Temperature within the monitoring system may be monitored in order to provide compensation for the signals produced by the optical detectors. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.
