LASER INDUCED BREAKDOWN SPECTROSCOPY (LIBS)

Laser Induced Breakdown Spectroscopy (LIBS) is emission spectroscopy of plasma , generated due to laser spark induced ablation and excitation. Laser induced breakdown and plasma generation can occur with solid , liquid or gaseous and the ablated sample size is typically a few micrograms. This technique is fast emerging as an important tool for chemical analysis which is highly sensitive and minimally destructive.

LIBS is used for the detection of Beryllium in Be treated sapphires and filler elements like Lead, Lithium, Boron, Silicon etc in fracture filled gemstone. which could be used as a confirmation test for borosilicate glass treatment.
