  • LIGHT SOURCE ACCOMMODATION FOR DIFFERENT SAMPLE MATRICES
    Publication number: 20220155230
    Abstract: Provided herein are methods for accommodating for sample matrix effects in light measurement assays. A selected amount of a light emitting material is added to a sample, and the light output from the sample is measured. By using an algorithm based on the known light emitting material amount and the measured light output, a correction factor for the assay of the sample is determined. The correction factor can be used to adjust subsequent light output measurements of other samples recorded using the assay.

  • Analyzer
    Patent number: 11119043
    Abstract: Provided herein are analyzers as well as related methods for measuring both an absorbance and emission of a sample. The analyzer includes light sources for epi-illumination and transillumination of the sample, and detectors for measuring the intensities of excitation, emission, and transillumination light. A dichroic mirror permits a portion of the excitation light to transmit to a detector that monitors changes in excitation light intensity. Temperature sensors allow for signal corrections based on temperature variations of the detectors and sample.
