Enhanced light collection in a flow cytometer

M H Fox, J R Coulter

    Cytometry
    |July 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Light collection efficiency in flow cytometry is significantly improved. A modified flow cell with a plano-convex lens and secondary sheath doubles light collection and enhances operational stability.

    Background:

    • Conventional flow cytometers utilize flow cells for cellular analysis.
    • Light refraction at the flow cell-to-air interface causes significant signal loss.
    • Existing flow cell designs may limit optimal light collection efficiency.

    Purpose of the Study:

    • To analyze light refraction in a modified flow cell.
    • To improve light collection efficiency in flow cytometry.
    • To enhance the operational stability of flow cells.

    Main Methods:

    • Modification of a conventional flow cell.
    • Analysis of light refraction at the flow cell-to-air interface.
    • Addition of a plano-convex lens and a secondary sheath to the flow cell.
