ICP Elemental Analysis: from Sample Introduction to Matrix Effects. Instructor: José-Luis Todolí (Department of Analytical Chemistry, Nutrition and Food Science, University of Alicante, P.O. Box 99, 03080 Alicante, Spain, email@example.com)
This short course deals with practical aspects regarding the elemental analysis using both Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and Mass Spectrometry (ICP-MS). A first chapter contains the description of the design and operating principles of liquid sample introduction systems including nebulizers, spray chambers and desolvation systems. Attention will be paid to the analysis of microsamples requiring the use of the so-called low sample consumption systems. Advice about the selection of suitable devices according to the application considered as well as those aimed at optimizing the performance of the ICP spectrometer will be given.
Interferences are still one of the most severe problem faced by plasma spectrochemistry. They can be classified as spectral and non-spectral phenomena. The different sources of interferences will be thoroughly discussed in a second part of the present course. Matrices will be classified as inorganic acids, easily ionized elements and organics. Methods to alleviate and/or to remove matrix effects will be discussed. As a representative example, the analysis of petroleum products and biofuels through ICP will be the focus of the course final part. This analytical challenge will be considered from the point of view of sample preparation, introduction, signal optimization and speciation.
Laser Ablation Inductively Coupled Plasma Mass Spectrometry. Instructor: Henry Longerich (Earth Sciences, Memorial University of Newfoundland, St. John’s, NL A1B 3X5, Canada, firstname.lastname@example.org)
While the emphasis of this course deals with the fundamentals of laser ablation (LA) sample introduction into an inductively coupled plasma mass spectrometer (ICPMS), this course will start with a personal early history of ICPMS, which I first “discovered” in 1983. Shortly after, in the spring of 1984, the first ELAN 250 instrument was delivered by the Ontario company SCIEX to the National Research Council of Canada, an Ottawa, Ontario laboratory. Just before Christmas in 1984, we installed the tenth commercially delivered instrument from SCIEX. A few years later, in 1989, we built our first LA system for applications emphasizing the micro analysis of development of both the ICPMS and later the LA systems, and a recommendation to look for the major advance in elemental and isotopic analysis, which is long overdue.
A discussion will follow concerning the ICPMS, which is a fundamental component of a complete (LA-ICPMS) system, including most importantly the detectors, system settling times, and the operator choices of data acquisition parameters. Understanding of these components of the ICPMS are essential for data interpretation, the production of quality results, as well as assisting a buyer in choosing among available commercial instruments, noting that some special considerations should be made when purchasing an ICPMS for LA applications. Details of LA systems in general, with a special detailed discussion on choices of lasers, laser induced elemental fractionation, and analytical detection limits will be included.
Practical Aspects of Trapped Ion Mass Spectrometry: Theory and Instrumentation. Instructor: Raymond E. March, Trent University, Peterborough, ON (email@example.com)
Introduction. In the movie Ben-Hur, an exciting race between horse-drawn chariots is held within the confines of a somewhat elliptical Roman arena. The race consisted of ten complete circuits of the arena, and the progress of the race was indicated on a scoreboard. As each circuit was completed, a fish-like marker was swung down to record the progress of the race, much like a scoreboard for a hockey game. Several such arenas exist to this day. The advantages of an arena race, as opposed to a linear flow along a runway, is that observation of the runners is prolonged and the motion of each participant can be detected throughout the race. The concept of prolonged ion confinement with continuous observation has been recognised for some decades in the mass spectrometry field; several forms of ion-trapping devices have been developed. An interesting outcome of ion confinement has been the observation of high mass resolution. When resolution is defined as the ratio of the mass m of an ion to the half-height width Δm of the ion peak, mass resolution to 107 is now achievable.

Risk Assessments on Nanomaterials. Instructor: Petra Krystek (Vrije University (VU) Amsterdam, Amsterdam, The Netherlands, firstname.lastname@example.org)
This course will provide an overview about the role of analytical techniques (especially inductively coupled plasma mass spectrometry (ICPMS) and complementary techniques) in the characterization of (engineered) nanomaterials, the analysis of (contact) matrices from human exposure scenarios to nanoproducts as well as in assessments regarding occupational exposure.
The stepwise procedures from sampling, sample pre-treatment and measurements by ICPMS will be discussed while aspects of validation and quality control will be involved too. In these cases, ICPMS is used for elemental identification and quantification. The possibilities by single particle (sp) ICPMS will be shown as well.
The knowledge on exposure and possible toxicity of nanotechnological products is growing but still limited, resulting in a great relevance of human risk assessments while external exposure can occur by inhalation, ingestion, injection and/or skin contact. In addition, internal exposure (e.g (bio)distribution) is of concern too. For answering all these questions, integrated approaches based on the use of ICPMS including hyphenation to e.g. asymmetric flow field flow fractionation (AF4) and other complementary techniques are needed. An overview about the selection criteria of matrices and analytical procedures by ICPMS will be given. Examples with e.g. body fluids, saliva, tissues (organs) and skin will be discussed more closely.
The course will be given as interactive training; on request, aspects like e.g. environmental assessments or exposure models can be touched too.
Speciation analysis: from state of the art to the development of simplified versions for the routine analysis. Instructor: Joerg Feldmann (University of Aberdeen, Scotland, UK email@example.com)
The elements arsenic and mercury are chosen since arsenic is symbolized as an element with a plethora of elemental species occurring naturally in the environment (more than 100 species) while mercury speciation focusses mainly on elemental, inorganic and methylmercury.
The course will cover targeted analysis for popular speciation analysis such as inorganic arsenic in rice using HPLC-ICPMS (high performance liquid chromatography coupled to inductively coupled plasma mass spectrometry) and will expand to arsenolipids analysis as a typical non-targeted analysis using HPLC-ICPMS/ESIMS (electrospray ionization mass spectrometry) in order to quantify and identify novel arsenic species in biological and environmental samples. A simplification of the targeted analysis will be illustrated by using discriminative hydride generation (HG) for inorganic arsenic in rice so that speciation can be done without HPLC by simply HG-ICPMS without a bias. Furthermore, it will be illustrated that we can replace ICPMS with not only AFS (atomic fluorescence spectrometry) but with a field deployable kit based on the Gutzeit method, so that determination of inorganic arsenic in the rice can be done within one hour in the field with this validated method.
In terms of mercury, mercury analysis for methylmercury and inorganic mercury can be done as state of the art by species-specific isotope dilution GC (gas chromatography)-ICPMS. This has been useful but only a few labs can do this. A simplified version developed also in our lab uses online SPE (solid phase extraction)-HPLC-CV (cold vapour generation)-AFS to measure detection limits in the lower ppq range and is therefore useful for the determination of methylmercury in seawater, sewage water, sediments and foodstuff such as rice. If time permits, speciation analysis of mercury beyond methylmercury will be covered, which will used HPLC-ICPMS/ESIMS for the detection of mercury and methylmercury biomolecules such as mercury phytochelatins in plants.
