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.
