Abstract:
Described herein are methods and apparatus for spectroscopic analysis of samples. In many embodiments, an apparatus for providing spectroscopic analysis of a sample comprises a sample holder. For example, the sample holder may comprise a consumable single use sample holder that can be readily coupled to and removed from a measurement apparatus such as a spectrometer. The sample holder may comprise a measurement surface configured to receive the sample during measurement, wherein the measurement surface may comprise a porous mesh. The porous mesh can receive the sample to optimally configure the sample for spectroscopic measurement, as described in further detail herein.
Abstract:
The present application describes a NIR spectrometer for label-free, rapid, portable and high-precision molecular composition analysis of a sample. The NIR spectrometer is integrated in a lab-on-chip and comprises a broadband NIR source configured to generate NIR light pulses; collimating and focusing objectives; a PDMS chamber mounted on a silicate glass support and designed to be filled with the sample and to receive an NIR light beam from a channel waveguide; the cannel waveguide built in a silicate glass support and configured to transmit the NIR light beam through the sample; an optical spectrum analyser configured to receive the NIR light beam, partially absorbed by the sample, and to measure an output signal intensity of the light beam versus a wavelength of said light beam; optical fibres connecting the components of the NIR spectrometer; and a computing unit.
Abstract:
Aspects of blending data detected by a monochromator over multiple wavelength ranges is described herein. In one embodiment, the monochromator includes a diffraction grating, a grating drive motor that rotates the diffraction grating to provide, by diffraction of broadband light, first dispersed wavelengths of light and second dispersed wavelengths of light, a detector that detects a first reflection from the first dispersed wavelengths of light and a second reflection from the second dispersed wavelengths of light, and processing circuitry that blends data values from the first reflection and data values from the second reflection together to provide a spectrum of combined data values. By blending data detected over multiple ranges, measurements of relatively high precision and quality can be provided over a wider spectral range.

Abstract:
A liquid sample introduction system for a plasma spectrometer includes a sample container for holding a liquid sample, a surface acoustic wave (SAW) nebulizer, arranged to receive a liquid sample from the sample container, an electronic controller for supplying electrical power to the SAW nebulizer so as to produce a surface acoustic wave on a surface of the SAW nebulizer, for generating an aerosol from the supplied sample liquid, and an aerosol transport arrangement for receiving the aerosol from the SAW nebulizer and carrying it into a plasma or flame of a spectrometer. The electronic controller is further configured to control the electrical power to the SAW nebulizer so as to permit adjustment of the aerosol parameters, and to control the aerosol transport arrangement so as to permit adjustment of the aerosol delivery into the plasma or flame of the spectrometer.
