Experience in instrumentation, field, and laboratory experiments
For my doctoral research, I used various aerosol samplers and conducted many field campaigns in urban, rural, and remote locations in India. Listed below are the various state-of-the-art instruments that I have used for physico-chemical characterization of aerosol particles.
Focused Ion Beam coupled with Scanning Electron Microscope and Energy Dispersive X-Ray Spectrometer (FIB-SEM-EDS).
Wavelength Dispersive X-ray Fluorescence Spectrometer (WD-XRF)
Fourier Transform Infrared Spectrometer (FTIR)
X-ray Photoelectron Spectrometer (XPS)
At Indian Institute of Technology:
Conducted experiments using Potential Aerosol Mass (PAM) coupled with:
Aerosol Chemical Speciation Monitor (ACSM)
X-ray Fluorescence Spectrometer (Xact)
Proton Transfer Reaction - Time of Flight - Mass Spectrometer (PTR-ToF-MS)
Scanning Mobility Particle Sizer (SMPS)
Seven wavelength Aethalometer (AE33)
Various gas analyzers (CO, NOx, SO2, O3, VOC)
