Sažetak
In agriculture, elemental plant analysis is one of the most important steps towards efficient crop production. The information obtained through elemental analyses are a useful guide for crop producers and breeders how to estimate nutritional status and improve fertilizer effectiveness in plants, stress resistance, quality of crops and crop products, and developing diseases. Currently available analytical methods involve complex and extensive sample preparation which usually makes them time-consuming and expensive. One of the most attractive alternative analytical methods that allows rapid, in-situ and multi- elemental analysis is laser-induced breakdown spectroscopy (LIBS). In this experiment we demonstrated the potential of femtosecond pulse, MHz pulse repetition rate, nJ pulse energy level, LIBS (fs-nJ-LIBS) for the determination of elements in wheat. The laser generated 160 fs pulses, with 30 nJ energy, 80 MHz pulse repetition rate, and centered spectrum at 1030 nm. In obtained spectra, we identified chemical elements in our sample. We are working on setup improvements to increase the signal-to-noise ratio in order to enable elemental concentration determination from fs- nJ-LIBS spectra.
