    Abstract: The invention generally relates to methods for determining a concentration of at least one target analyte in a heterogeneous sample and methods for detecting a condition. In certain aspects, the inventions provides methods that involve illuminating a heterogeneous sample, such as a biological sample, including at least one target analyte with polychromatic light, receiving luminous data of the heterogeneous sample and the at least one target analyte with a detector without splitting the polychromatic light into individual wavelengths and generating spectral data therefrom. The spectral data is then converted into a concentration of the at least one target analyte in the biological sample by comparing the spectral data to a database comprising known spectra already associated with concentration levels.

    Abstract: A fluid separation system for separating compounds of a sample fluid in a mobile phase comprises a detector adapted to detect separated compounds by providing an optical stimulus signal to the sample fluid and receiving a response signal on the optical stimulus signal. The detector comprises a light source adapted to provide an output light beam as the optical stimulus signal. The light source comprises a plurality of light emitting elements each adapted to emit a light beam having a respective wavelength, and a diffracting element. The plurality of light emitting elements are arranged that emitted light beams impinging on the diffracting element in a respective angle dependent on the respective wavelength are diffracted by the diffracting element into the output light beam.

    Abstract: In detecting presence of a gas, light passes through a photonic crystal cavity configured to sample a gas and receive light. The light has a wavelength that at least partially falls within a specific absorption wavelength of the gas. At least one parameter of a band gap spectrum is generated from at least a portion of the light passing through the photonic crystal cavity. In generating the at least one parameter, a numerical simulation is performed within a frequency range of the photonic crystal cavity to generate a set of spectral response data points, rational function interpolation is performed on the set of spectral response data points to generate a spectral response, and at least one parameter is determined from the spectral response. The at least one parameter is compared with stored parameters of band gap spectrums, wherein a match indicates a presence and/or concentration of the gas.

    Abstract: A set of spectral data is collected from a mixture and corrected to remove instrumental artifacts. The collected mixture spectra define an n-dimensional data space, where n is the number of data points in the spectra. Principal component analysis (PCA) techniques are applied to the n-dimensional data space to generate and select a subset of m eigenvectors that effectively describe all variance in the original data space. The members of a spectral library of known, pure components are examined based on this reduced dimensionality data space using target factor testing techniques. Each library spectrum is represented as a vector in the m-dimensional reduced data space, and target factor testing results in an angle between the library vector and the data space for each spectral library member. Those spectral library members that have the smallest angles with the data space are considered to be potential members, or candidates, of the mixture and are submitted for further testing. The spectral library members are ranked and every combination of the top y members is considered as a potential solution to the composition of the mixture. A multivariate least-squares solution is then calculated using the mixture spectra for each of the candidate combinations. Finally, a ranking algorithm is applied to each combination and is used to select the combination that is most likely the set of pure components in the mixture.
