Abstract In this work, we investigate the impact of data provided by complementary laser-based spectroscopic methods on multivariate classification accuracy. Discrimination and classification of five Staphylococcus bacterial strains and one strain of Escherichia coli is presented. Obtained spectroscopic data were then processed using Multivariate Data Analysis algorithms. Principal Components Analysis PCA was selected as the most suitable technique for visualization of bacterial strains data.
THAKUR About the book By table of contents Book description Laser induced breakdown spectroscopy LIBS is basically an emission spectroscopy technique where atoms and ions are primarily formed in their excited states as a result of interac The interaction between matter and high-density photons generates a plasma plume, which evolves with time and may eventually acquire thermodynamic equilibrium.
One of the important features of this technique is that it does not require any sample preparation, unlike conventional spectroscopic analytical techniques. Samples in the form of solids, liquids, gels, gases, plasmas and biological materials like teeth, leaf or blood can be studied with almost equal ease.
LIBS has rapidly developed into a major analytical technology with the capability of detecting all chemical elements in a sample, of real- time response, and of close-contact or stand-off analysis of targets.
The present book has been written by active specialists in this field, it includes the basic principles, the latest developments in instrumentation and the applications of LIBS.
It will be useful to analytical chemists and spectroscopists as an important source of information and also to graduate students and researchers engaged in the fields of combustion, environmental science, and planetary and space exploration.

Nuclear Magnetic Resonance Spectroscopy. 1.
Background Over the past fifty years nuclear magnetic resonance spectroscopy, commonly referred to as nmr, has become the preeminent technique for determining the structure of organic compounds. Of all the spectroscopic methods, it is the only one for which a complete analysis and interpretation of.
Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. The laser is focused to form a plasma, which atomizes and excites samples. Laser induced breakdown spectroscopy (LIBS) is basically an emission spectroscopy technique where atoms and ions are primarily formed in their excited states as a result of interaction between a tightly focused laser beam and the material sample.
The interaction between matter and high-density photons generates a plasma plume, which evolves.
Laser-induced breakdown spectroscopy (LIBS) offers the ability to analyze soil samples with little sample preparation, provides detection of all elements in the periodic table, and has a large dynamic range (ppm to wt.
%). Laser-induced breakdown spectroscopy (LIBS) is an atomic emission spectroscopy. Atoms are excited from the lower energy level to .
