    摘要: Described herein are apparatuses for analyzing an optical signal decay. In some embodiments, an apparatus includes: a source of a beam of pulsed optical energy; a sample holder configured to expose a sample to the beam; a detector comprising a number of spectral detection channels configured to convert the optical signals into respective electrical signals; and a signal processing module configured to perform a method. In some embodiments, the method includes: receiving the electrical signals from the detector; mathematically combining individual decay curves in the electrical signals into a decay supercurve, the supercurve comprising a number of components, each component having a time constant and a relative contribution to the supercurve; and numerically fitting a model to the supercurve.

    摘要: An apparatus to provide a label-free or native particle analysis comprises a light generating system producing first light pulses at a first wavelength and second light pulses at a second wavelength; and a flow cell coupled to the light generating system to convey particles for analysis. The light generating system is configured to chirp at least one of the first light pulses and the second light pulses to analyze the particles.
