Abstract:
1. A flow cytometer, comprising: a laser light source, configured to emit a first light beam having a first spectrum width and irradiating a solution including target particles and being flowed in a flow cell to generate forward scattered light and orthogonal scattered light therefrom; a light emitting diode, configured to emit a second light beam having a second spectrum width broader than the first spectrum width and irradiating the solution in the flow cell to generate at least one wavelength of fluorescence therefrom; a first detector, adapted to detect the forward scattered light; a second detector, adapted to detect the orthogonal scattered light; at least one third detector, adapted to detect the at least one wavelength of fluorescence; a first filter, disposed between the flow cell and the third detector and adapted to eliminate scattered light generated from the target particles by the irradiation of the first light beam; a second filter, disposed between the flow cell and the first detector and adapted to eliminate scattered light generated from the target particles by the irradiation of the second light beam; and a third filter, disposed between the flow cell and the second detector and adapted to eliminate scattered light generated from the target particles by the irradiation of the second light beam.
