In this work a complex study of the capabilities Particle Induced X-Ray emission(PIXE) technique for the determination of minor constituents of aerosol samples has been done.The PIXE experiments were carried out at Cyclotron at Department of Physics, Panjab University Chandigarh using ~2.7MeV proton beam. The X-rays were detected with the help of low energy HPGE detector. Total fifteen samples were collected from various locations in Chandigarh.The minor elements identified in the aerosol samples wereS,Cl,K,Ca,Ti,Cr,Mn,Fe,Ni,Zn,V,Br and Pb. The data analysis was done using GUPIX software to extract the quantity of the trace elements.

Experimental results are presented obtained with a cryogenically cooled high-resolution X-ray spectrometer based on a 141 × 141 µm Nb-Al-Al2O3-Al-Nb superconducting tunnel junction (STJ) detector in an SR-XRF demonstration experiment. STJ detectors can operate at count rates approaching those of semiconductor detectors while still providing a significantly better energy resolution for soft X-rays. By measuring fluorescence X-rays from samples containing transition metals and low-Z elements, an FWHM energy resolution of 6–15 eV for X-rays in the energy range 180–1100 eV has been obtained. The results show that, in the near future, STJ detectors may prove very useful in XRF and microanalysis applications.
