Measurements of toxic heavy metals in liquid samples using Laser-Induced Breakdown Spectroscopy
Original language description
Laser-Induced Breakdown Spectroscopy (LIBS) is a spectroscopic technique for real-time semi-quantitative and qualitative analysis of samples in different phases of matter (solid, liquid, gaseous). LIBS can be applied among others to study of aqueous solutions even with trace element content, e.g. for measurements of environmental water pollution. Here the measurements of trace amounts of heavy metals in liquid samples using LIBS are discussed. The newly constructed modular apparatus for liquid samples can be directly attached to the current experimental setup of single-pulse and double-pulse LIBS (SP and DP LIBS). The narrow steady flow of the investigated liquid is realized with combination of peristaltic pump and in-house made jet. Second harmonic frequency of pulsed Nd:YAG laser (Brilliant B, Quantel) is used for plasma creation. The laser beam is focused on the liquid flow, small amount of liquid sample is ablated and radiating micro-plasma is created. The plasma emission is collected by a custom-
