Analysis of Edible Silver Foils Under Steady Magnetic Field by Calibration Free Laser Induced Breakdown Spectroscopy (CF-LIBS)
The Rudimentary Analysis of Edible Silver foil has been Investigated by a Magnetic Field (B)-supported LIBS. The Silver Plasma was Produced by Employing an Nd-YAG Pulsed Laser (100 mJ,1064 nm,) on the Surface of Silver foil in the Presence of B = 0.75 T, which Analyzed the Significant Enhancement in the LIBS Sensitivity by Detecting the Essential and Toxic Elements (C, Ag, Al, Fe, Ca, Cr, Si, Mg, Na) in Silver Plasma. The Enhancement Factor is up to four-fold and Optical Emission Intensity, Plasma Parameters like Plasma Temperature (Te) and electron Number Density (ne) were Enhanced in the Presence of a Magnetic Field (B). The Signal Enhancement in Silver Plasma was Ascribed to Magnetic Confinement and an Increase in Recombination rate after Relaxing the Plasma. Moreover, the Value of Thermal beta is Estimated Analytically (βt < 1) in this Study, which Confirms the Validity of Magnetic Confinement in all Samples. The Elemental Composition was Determined by the Calibration-Free LIBS (CF-LIBS) Approach with Zero Fields and B-field. The Result Revealed that Silver Foils were Fraudulently Adulterated by 25–35% Aluminum, and 0.8–1.08% Chromium, which Eventually Accumulates in the Human body via the food Chain Leading to high Risks to Human Health
