Book Description
Time of flight mass spectrometry identifies the elements of a compound by subjecting a sample of ions to a strong electrical field. Illuminating emerging analytical techniques in high-resolution mass spectrometry, Liquid Chromatography Time-of-Flight Mass Spectrometry shows readers how to analyze unknown and emerging contaminants—such as antibiotics, steroids, analgesics—using advanced mass spectrometry techniques. The text combines theoretical discussion with concrete examples, making it suitable for analytical chemists, environmental chemists, organic chemists, medicinal chemists, university research chemists, and graduate and post-doctorate students.

Book Description
This book provides an overview of the phenomenology, technology and application of secondary ion mass spectrometry as a technique for materials analysis. This approach is developing into one of the most effective methods of characterizing the composition and chemical state of the surface and sub-surface layers of solid materials. The first three chapters introduce the basic physical and chemical principles involved and the theories which have been proposed to explain the process. Subsequent chapters describe the instrumental components of the SIMS apparatus, the use of SIMS as an analytical tool, and the development of the techniques of sputtered neutral mass spectrometry and laser microprobe and plasma desorption mass spectrometry. Many practical examples are featured to illustrate the application of SIMS to real problems, possible pitfalls are pointed out, and data of use to analysts are collected in appendices. The book is a practical guide suitable for scientists in all fields who wish to use this valuable analytical technique.

Book Description
This book was written to explain a technique that requires an understanding of many details in order to properly obtain and interpret the data obtained. It also will serve as a reference for those who need to provide SIMS data. The book has over 200 figures and the references allow one to trace development of SIMS and understand the many details of the technique.

Book Description
Forensically significant samples, such as drugs and propellants can be analysed using a range of standard techniques like Hight Performance Liquid Chromatography (HPLC) and Gas Chromatography Mass Spectrometry (GCMS). These methods can often be time-consuming, require complex sample preparation or extraction, with multiple steps and additional components. The drug samples investigated are those that have been inlaid in fibres, in this form to either mimic oral fluid based roadside drug tests or drug laden clothing and other fabrics used in smuggling cases. The analysis of these samples is important and can be complicated by the need for extraction of the analytes from the fibres and the possible destruction of evidence required to perform said analysis. -- Laser Desorption Ionization (LDI) techniques are an intriguing alternative to these standard techniques as they can perform high throughput analysis with little sample preparation and often generate simple spectra. LDI is highly sensitive and specific and is compatible with less stable sample-types. -- The initial issue for LDI analysis of drug samples was associated with low mass interference experienced when such low mass analytes encounter similar mass matrices. Several alternatives to traditional matrices were explored, and it was successfully overcome for on-plate and fibre-based analyses using a layer of gold nanomaterials which provided increased laser absorption without the low mass interference. -- LDI was also explored as a method of analysing complex propellant samples. Propellants contain several different species, which vary among manufacturers and as samples age. They often require multiple techniques for their analysis with different sample preparation techniques. LDI was compared to standard techniques as well as some more interesting alternatives, to successfully differentiate several diverse propellant samples.
