Presented by Isaac (Joe) Brenner, Brenner Scientifc
Tuesday, October 5, 2021 ◉ 1:00 pm to 3:00 pm EST
TARGET AUDIENCE: This course is intended for all laboratory personnel – operators, managers, quality control and assurance specialists, research scientists, environmental chemists, geochemists, biologists, metallurgists, toxicologists, new and experienced users of atomic absorption and plasma spectrometry, and technical personnel at all levels.
COURSE DESCRIPTION: Overview and description of ICP-AES technologies. Comparison with Microwave Induced Plasmas. Advantages of low UV wavelength range for determination of halogens and other elements. Developments in axially, radially’, dual, side-on, dual side viewed plasmas. Comparison using LODs, linearity, and EIE matrix effects. Evaluation of plasma observation configurations and robust conditions – MgII/Mg I ratios and minimum EIE effects Cross-over point – Vertical intensity variations and regions of minimum easily ionized element interference effects. Enhancement effects due to addition of C-species. Brief overview of the DC carbon Arc AES, slurry nebulization and spark ablation for direct solids analysis. Requirements for ISO 17025 accreditation. Overcoming hurdles of sample preparation.
About Joe Brenner
Dr. Brenner is a forerunner in implementation of new instrumentation and methodologies for analysis of emerging contaminants in environmental samples. At present he is a pioneering educator and project leader on application of qPCR and NGS for detection and enumeration of pathogenic bacteria and viruses – specifically SARS Covid-2 in biosolids and wastewater. As educator, he describes the cycle of SARS CoVid-2, including sampling, extraction, enumeration, confirmation and NGS sequencing. Brenner obtained his PhD at the Hebrew University and was a senior scientist in Application and R and D in Jobin Yvon, France, Varian Research Center at Palo Alto and application adviser for Mass Spectrometry at Thermo Scientific in Spain and UK.
