Abstract: A spectrometer, such as a Raman spectrometer, adapted for analyzing a complex sample is provided. In an example implementation, the spectrometer may be able to determine one or more spectral characteristics of an inner subsurface layer or region of a complex sample (e.g., contents of a container). In one embodiment, for example, A spectrometer includes an excitation source configured to provide an excitation signal; an optical system configured to direct the excitation signal toward a sample and receive a spectroscopy signal from the sample. The optical system may include a spatial filter configured to separate or isolate at least one first portion of the spectroscopy signal from at least one second portion of the spectroscopy signal and pass the at least one first portion of the spectroscopy signal. A detector is configured to determine at least one spectral feature of the at least one first portion of the spectroscopy signal.

Abstract: A lotto scratch pad and method of collecting scrapings, in general, a holding device having a backer board or hard surface with a clasp or clip attached thereto and positioned approximate one edge of the backer board, at least one collection bin, compartment, trough or receptacle positioned on another edge of the backer board having a hinged tab to enclose lotto ticket shavings therein and, thus, functions to collect and contain any scrapings created as a player scratches the opaque covering off scratch tickets on the holding device.

Abstract: A method for prophylaxis against human cancer which comprises the administration of chelating or complexing agents capable of removing from the human body the various isotopic forms of lead and their radioactive precursors.
