| dc.description.abstract | In this work we have constructed a functioning Nitrogen lasers with different electrode materials and different sized aluminum foil capacitors with success. With the result we went ahead with the Raman spectroscopic study of polystyrene sample, which is used as food packaging material and as insulator in transportation of fragile materials, and acquired the standard spectra of polystyrene found in reference spectral database with a close Raman shift of Raman peak values. We also pumped Rhodamine 6G dye successfully and used the dye laser for the fluorescence spectroscopic study of edible niger seed oil. We have seen that there is a linear relationship of contamination of the pure niger seed oil with that of heated niger seed oil simulating a used oil in cooking food. We have been able to detect a minimum of 1.61% contamination and show that there might be a new fluorophores formation due to the heating of the oil. | en_US |
