Technical Webinar on Laser Induced Breakdown Spectroscopy (LIBS)
Dr. Edenir Rodrigues Pereira Filho
Federal University of São Carlos (UFSCar – São Paulo State)
Applied Spectra, Inc. invites you to attend our technical webinar on Laser Induced Breakdown Spectroscopy (LIBS). This webinar highlights an overview of +10 years of analytical research work led by Dr. Edenir Rodrigues Pereira Filho at UFSCar in Brazil.
Prof. Edenir Rodrigues Pereira-Filho has conducted analytical research on LIBS since 2012 in Brazil. He has developed LIBS sampling methods and various calibration procedures for effective use of LIBS in the analysis of electronic wastes (WEEE), agricultural products (cocoa beans, sugar canes, etc.), fertilizers, dietary supplements, and archeological samples. In enabling LIBS for these analytical applications, he has developed and applied different calibration procedures involving both univariate and multivariate approaches. In this webinar, he will discuss some of these approaches that include Matrix Matching Calibration (MMC), Multi-Energy Calibration (MEC), Two Point Calibration Transfer (TP CT), Partial Least Square (PLS), Principal Component Regression (PCR) as well as data fusion involving multiple techniques (LIBS, LA-ICP-MS and XRF). Prof. Edenir Rodrigues Pereira-Filho will also provide a link to free E-book on LIBS and share a list of +40 papers covering a wide range of LIBS applications.

| The J200 instrument saga: ten years of analytical chemistry development using LIBS|
Prof. Edenir Rodrigues Pereira-Filho Federal University of São Carlos, Chemistry Department, Brazil
In this webinar, I am highlighting several analytical chemistry developments performed by my research group since 2013. These developments were performed using a J200 laser-induced breakdown spectrometry (LIBS) instrument from Applied Spectra. Univariate and multivariate calibration approaches were proposed to determine several elements in a myriad of samples, from hair, sugarcane, waste electrical and electronic equipment and food. The main goal is to present to the audience the possibilities that LIBS can offer to solve complex analytical problems.
Prof. Edenir Rodrigues Pereira Filho obtained B.S. degree in Chemistry from Pontifical Catholic University of Campinas – PUC-Campinas (Campinas, São Paulo State, Brazil) and MSc in Chemistry from the Chemistry Institute at Campinas State University (Unicamp). In 2001, he conducted a part of his doctoral research at the Institute of Spectrochemistry and Applied Spectroscopy (ISAS), Dortmund, Germany. In 2003, he obtained his Ph.D. in Sciences. His research has been dedicated to LIBS (Laser-induced breakdown spectroscopy), sample preparation, biological and environmental sample analyses, chemical imaging (digital and hyperspectral) and chemometrics application in analytical chemistry. Prof. Edenir Rodrigues Pereira Filho published more than 170 papers. In August 2006, he started professional activities at the Chemistry Department of São Carlos Federal University (UFSCar – São Paulo State) and to date, supervised 20 and 15 master and PhD students, respectively.
