This book was released on 2009 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Recent interest in the use of phyto-mapping for plume delineation at contaminated sites has promoted a need for new and innovative sampling techniques. Solid-phase micro-extraction (SPME) methods have been developed as a chemical analysis tool offering fast, simple, non-invasive sampling without the use of solvents. In this study SPME devices were tested for applicability for in-planta detection of chlorinated solvents. To evaluate the use of SPME for VOCs in-planta a number of integrated studies were undertaken. Uptake profiles were developed for nine chlorinated solvents in a liquid polydimethylsiloxane (PDMS) matrix with 100 [mu]m Carboxene SPME fibers. Timeweighted average (TWA) sampling was conducted by exposing the SPME fiber to the chemical mixtures using three retraction lengths. Linear uptake profiles were demonstrated for 25 of the 27 of the sampling conditions. A storage experiment was conducted to determine sample retention on the SPME fiber for transport prior to analysis. It was demonstrated that all chemicals except dichloromethane are retained on the fiber for up to 24 hours. Field sampling with SPME devices was conducted at a known chlorinated solvent contaminated site using a newly designed in-planta sampler. Sampling with SPME fibers produced detections ranging from 5 to 234 times higher than tree core sampling"--Abstract, leaf iii.

This book was released on 2023-03-24 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid Phase Microextraction (SPME) is a flexible and convenient sampling and sample preparation technique that extracts different kinds of analytes, including both volatile and non-volatile, without the use of a solvent. The technique facilitates fast, simple and automated determination of target analytes in a range of matrices. As it offers a green methodology, it is growing in popularity as an alternative tool in analytical chemistry to traditional methods. This book follows on in spirit from the editors' previous title, Applications of Solid Phase Microextraction and will introduce the reader to breakthrough methodologies and cutting edge applications. Although it assumes a good degree of SPME knowledge, an overview of the fundamentals is given before taking the reader through an update of the field. The reader will learn the basic principles and advantages of different SPME formats including the stir bar extraction techniques, thin film SPME, Bio-SPME, and new trends in different coatings. Applications in complex media, including food analysis, drug residues and bioanalysis are covered. Bringing together leading sample preparation academics from around the world, the editor has put together an informative new book, suitable for analytical chemists and practitioners utilising SPME tools in their research.

Available in PDF, EPUB and Kindle. Book excerpt: Monitoring pollutants in air, soil and water is a routine requirement in the workplace, and in the wider environment. Passive samplers can provide a representative picture of levels of pollutants over a period of time from days to months by measuring the average concentrations to which they have been exposed. Air monitors are widely used, for instance to measure the exposure of workers to volatile compounds, but also for monitoring the fate of pollutants in the atmosphere. Passive sampling devices are now becomining increasingly used to monitor pollutants in rivers, coastal waters and ground water where contamination results from sources such as domestic and industrial discharges, and the use of agrochemicals. Passive Sampling Techniques in Environmental Monitoring provides a timely collection of information on a set of techniques that help monitor the quality of air, surface and ground waters. Passive sampling can provide an inexpensive means of obtaining a representative picture of quality over a period of time, even where levels of pollutants fluctuate due to discontinuous discharges or seasonal application of chemicals such as pesticides. Recent changes in legislation have increased the pressure to obtain better information than that provided by classical infrequent spot sampling.Brought together in one source, this book looks at the performance of a range of devices for the passive sampling of metals, and of non-polar and polar organic chemicals in air and in water. The strengths and weaknesses and the range of applicability of the technology are considered.* Comprehensive review of passive sampling - covering air, water and majority of available technologies in one volume* Chapters written by international specialist experts * Covers theory and applications, providing background information and guidelines for use in the field
