The invention concerns methods for measuring sulfur content in a fiber or polymer resin sample comprising: a) contacting the sample with a solution comprising sodium hydroxide to convert sulfur to sodium sulfate, b) combusting the sample of step a) in a furnace to remove essentially all organic materials to produce a residue; c) dissolving the residue in concentrated nitric acid; and d) determining the sulfur content of the sample using ICP Emission Spectrometry.
Abstract:
The present invention is a method of determining the presence of keratin, particularly hard keratin, such as exists in mammalian hair and feathers, and objects comprising such materials. The method of the present invention also includes displaying information derived from such a determination, as well as a measurement method followed by transmission of data to a remote processing site for analysis or display. The invention also includes devices for carrying out the determination, display and/or transmission.
Abstract:
A cavity ring-down system for performing cavity ring-down spectroscopy (CRDS) using optical heterodyne detection of a ring-down wave (ERD) during a ring-down phase or a ring-up wave (ERU) during a ring-up phase. The system sends a local oscillator wave (ELO) and a signal wave (ESIGNAL) to the cavity (18), preferably a ring resonator, and derives an interference signal from the combined local oscillator wave (ELO) and the ring-down wave (ERD) or ring-up wave (ERU). The local oscillator wave (ELO) has a first polarization and the ring-down wave (ERD) has a second polarization different from the first polarization. The system has a combining arrangement (30) for combining or overlapping local oscillator wave (ELO), and the ring-down wave (ERD) at a photodetector (42), which receives the interference signal and generates a heterodyne current (IH) therefrom. Frequency and phase differences between the waves are adjustable.
Abstract:
Integrated computational elements having alternating layers of materials may be problematic to configure toward mimicking some regression vectors. Further, they sometimes may be inconvenient to use within highly confined locales. Integrated computational elements containing a quantum dot array may address these issues. Optical analysis tools with an integrated computational element can comprise: an electromagnetic radiation source that provides electromagnetic radiation to an optical pathway; an integrated computational element positioned within the optical pathway, the integrated computational element comprising a quantum dot array having a plurality of quantum dots disposed at a plurality of set array positions; and a detector that receives the electromagnetic radiation from the optical pathway after the electromagnetic radiation has optically interacted with a sample and the integrated computational element. Optical interaction of electromagnetic radiation with the quantum dots at one or more set array positions can substantially mimic a regression vector for a sample characteristic.
Abstract:
A handheld LIBS spectrometer system features an optics stage moveable with respect to a housing and including a laser focusing lens. A laser source is mounted in the housing for directing a laser beam to a sample via the laser focusing lens. A detection fiber is mounted in the housing and is fixed relative thereto. A first mirror is fixed relative to the housing and includes an aperture for the laser beam. This mirror is oriented to re-direct plasma radiation for delivery to the detection fiber. A controller subsystem is responsive to the output of a spectrometer subsystem and is configured to control the laser source and the optics stage.
