The purpose is testing the distribution of trace elements rapidly in apples by laser-induced breakdown spectroscopy. Used the 1064 nm and Q ns Nd:YAG laser to be the light source, high precision spectrometer collected spectrum. Layered the sample to four different part for experiments. Analysing spectrum of LIBS, obtained the characteristics spectrum of each elements. Research the time evolution and...
By detecting the chromium (Cr) element intensity in soil for the different analytical spectra lines by laser induced breakdown spectroscopy (LIBS) technique, which is made up with an Nd: YAG ns laser at 1064 nm and a multichannel spectrometer with ICCD detector, DG535, computer and optical devices. And using the obvious quantitative methods that make use of the absolute intensity, the relative intensity...
By detecting the nutrient elements contents in soil for monitoring the rice growth and conditions of nutrients, a month after fertilization N, P, K and no fertilization in paddy soil have been analyzed by laser induced breakdown spectroscopy (LIBS) technique, which is using a Nd: YAG ns laser at 1064 nm and an eight-channel AvaSpec spectrometer with CCD detector. The characteristic spectra and the...
Laser induced breakdown spectroscopy (LIBS) has become a powerful tool for the direct analysis of a large variety of materials in order to provide qualitative and/or quantitative information. However, there is a lack of information for LIBS analysis of biological samples. In this work, the spectra of E.coil, nutritional medium and filter paper have been analyzed by nanosecond LIBS. The samples were...
