    Experimental Techniques & Tools

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

    A cw-MHF-QCL based CRDS technique in the mid-infrared spectral region developed in our lab for studying high-resolution molecular spectroscopy, biomedical and environmental sciences.

    Residual gas analyzer (RGA) mass spectrometer for human breath analysis
    Image 02

    We have developed a RGA-based system for non-invasive diagnosis of Helicobacter pylori infection Type 2 diabetes and Irritable bowel syndrome.


    EC-QCL-based Wavelength Modulation Spectroscopy Technique in mid-IR region
