    Experimental Techniques & Instrumentation

    Quantum Cascade Laser (QCL)-based Cavity Ring-Down Spectrometer (CRDS)
    Image 01

    QCL based cw-CRDS techniques developed in our lab for studying high-resolution gas-phase spectroscopy in mid-IR spectral region.

    Residual gas analyzer (RGA) mass spectrometer for human breath analysis
