I'm looking to buy a good mass spec related book for my brother's graduation gift. He is graduating this fall and his master's thesis/studies is oriented in MS. Personally I don't have knowledge of chem/MS books so I'm asking for suggestions and recomendations.
Over the last decade, the use of ion mobility separation in combination with mass spectrometry analysis has developed significantly. This technique adds a unique extra dimension enabling the in-depth analysis of a wide range of complex samples in the areas of the chemical and biological sciences. Providing a comprehensive guide to the technique, each chapter is written by an internationally recognised expert and with numerous different commercial platforms to choose from, this book will help the end users understand the practicalities of using different instruments for different ion mobility purposes.
Please create your bookmark, if you are interested in learning about mass spectrometry, mass spectral interpretation, instrumentation, and the full range of ionization methods. Here, you find a total of about 100 pages with many exercises covering all 15 chapters of the book. Practicing MS becomes straightforward as each the problem pages is linked to a dedicated answer page.
In the light of an ever-growing abundance of methods, instruments, tools, and rules in mass spectrometry the ease of how a complex field of analytical science can be grasped mentally certainly deserves attention. Therefore, emphasis of my work was on refinement in terms of presentation, convenience of use, and ease of learning. Obviously, a textbook ranging around 900 pages may deter the novice, and thus, the focus was on a didactic and educational approach. Although the actual number of pages has notably increased once again, you will find the textbook easier to read and you will benefit when transferring theory in actual practice such as spectral interpretation and method selection.
Therefore, this third edition of the highly successful textbook, acclaimed for its comprehensiveness, accuracy, and excellent illustrations and photographs now comes with updated coverage plus numerous didactical improvements:
Numerous passages have been rewritten and improved while remaining short and concise. Care has been taken not only to explain how, but also why things are done a particular way.
The number of figures has been notably increased and about one third of them are now in full color. More photographs and schematics mean easier comprehension of contents, often providing valuable insight into the practical aspects of instrumentation and according procedures.
Flow charts have been introduced to describe procedures, approaches to mass spectral interpretation, or aid in decision making.
Bulleted enumerations have been introduced wherever a larger number of features, arguments, assumptions, or properties regarding a subject warrant a clear presentation.
More examples, especially of methods and applications are given and some how-to-style paragraphs provide practical guidance.
Examples and notes now come with a short subheading that immediately tells what the particular section is all about.
All chapters conclude with a concise summary that is subdivided into compact sections highlighting the basic concepts of the subject area, its figures of merit, typical applications, and its role in current MS. Chapter 4 (Instrumentation) provides dedicated summaries for each type of mass analyzers.
Digital object identifiers (DOIs) are included in the lists of references to facilitate the retrieval of references for e-book users. For those of you who, like me, still prefer a hard bound book, the DOIs offer an additional level of comfort.
Since the second edition, new techniques have gained importance and some instrumentation has received notable attention and attained considerable commercial success. To keep pace with recent developments, Chap. 4 now includes TOF instruments with folded flight paths, the dynamically harmonized FT-ICR cell, more on hybrid instruments and ion-mobility-mass spectrometry. The increasing relevance of high-resolution and accurate mass measurements is even stronger reflected in Chap. 3. The five chapters dedicated to soft ionization methods (CI, APCI, APPI, FAB, LSIMS, FI, FD, LIFDI, ESI, LDI, MALDI) as well as those on ambient desorption/ionization (DESI, DART, REIMS etc.) and on tandem mass spectrometry have been substantially updated and upgraded. There is also much more on chromatographic techniques (GC, LC) and their coupling to mass spectrometry in Chap. 14.
The way we are using books and literature in general has dramatically changed during the last decade. Today, even textbooks are being extensively used in their e-book versions. This had also some impact on the layout and production process of this book.
This title will not be in Indianapolis, but we will resume mail orders following the conference.
ASMS 50th Anniversary Volume
Measuring Mass: From Positive Rays to Proteins
Michael A. Grayson, ed.
This hardcover book was published to honor the 50th ASMS Conference in 2002, the book provides a glimpse of some of the important developments in the history of mass spectrometry, primarily in the United States..
Mass spectrometry (MS) is a powerful qualitative and quantitative analytical technique used to identify and quantify a wide range of clinically relevant analytes.[1] When coupled with gas or liquid chromatographs, mass spectrometers allow the expansion of analytical capabilities to various clinical applications.[2] In addition, because of its ability to identify and quantify proteins, MS is an essential analytical tool in the field of proteomics.[3]
Most mass spectrometry data are presented in units of the mass-to-charge ratio, or m/z, where m is the molecular weight of the ion (in daltons) and z is the number of charges present on the measured molecule.[4] For small molecules (
Atoms and molecules must first be ionized before they can be accelerated through the mass spectrometer and detected.[13] The sample molecule entered into the mass spectrometer will first get a positive charge from an ionization source. This positive charge is achieved by removing a valence electron. Protons can also be added to create a positive electrical charge. Next, the ionized molecule breaks apart into smaller fragments, then separated according to their mass-to-charge ratio in the mass analyzer.[1] Of note, only the cationic fragments are separated. The neutral species in the mass spectrometer goes undetected because it can be 1) absorbed by the apparatus or 2) removed by a vacuum. After the ions are separated, the detector will quantify the ions.[11]
A chart will be generated to analyze the mass spectrometer's results. The mass-to-charge ratio (m/z) is on the "x-axis," while the relative intensity is on the "y-axis." [12] For a given sample, the most abundant ion in the sample molecule is known as the base peak.[14] This ion is set to 100% on the y-axis for its relative intensity, and all the remaining ion peaks are generated relative to this value. The molecular ion peak is known as the parent peak because it corresponds to the molecular weight of the sample.[15] For example, if the specimen in the mass spectrometer was hexane, the m/z would be 86 since the molecular weight of hexane is 86 g/mol. Additionally, if there is a peak at m/z = 87, this would be classified as the m+1 peak because all atoms have various isotopes.[11]
Prior to using the mass spectrometer, a sample must be prepared for it to be ionized. Thus, samples are either in the liquid or gaseous phase by utilizing chromatography techniques. The two types of chromatography procedures that are used to prepare the sample are gas chromatography and liquid chromatography.[16]
Gas chromatography separates components of a mixture of gases and filters the passage of these molecules based on physical characteristics like shape, size, molecular weight, and boiling point. A sample is diluted and vaporized in the chromatograph, where it is separated. After separation, the gases enter the mass spectrometer for analysis. Notably, a gas chromatography sample must be volatile, meaning it must enter the gas phase so it does not break down while in the mass spectrometer apparatus.[17]
Liquid chromatography separates samples based on interactions with the mobile and stationary phases. This can be based on polarities, meaning that if a component of the specimen has a different polarity compared to the mobile phase, it will migrate down the chromatograph column faster. The sample is separated into bands into individual components that can be further analyzed in mass spectrometry.[18]
During ionization, the atoms are ionized by removing an electron to give off a positive ion known as a cation. Mass spectrometers only work with positive ions. Cations are formed regardless of the present state of the atoms. For example, this is true even if there is initially a negative ion in the sample, such as fluoride, or an element that does not form ions, such as neon.[22] Inside the mass spectrometer, an electrical field is generated that gives off electrons. These electrons will return to the electron trap, forming collisions to knock off the electrons to create cations.[23]
Electrospray ionization uses a combination of voltage, heat, and air to produce successively smaller droplets from the liquid, eluting off a chromatographic column.[30] The continuous loss of solvent concentrates these droplets, dramatically increasing charge per unit volume. Ions accumulated at the droplet surface desorb from the liquid into the gas phase, allowing these gas phase ions to enter into the mass spectrometer for analysis.[31] In addition, complete evaporation of the solvent liberates large ions, such as proteins, producing the necessary gas phase ions for analysis.[32]
All ions will undergo acceleration to have the same amount of kinetic energy. Cations will pass through slits in the mass spectrometer apparatus and accelerate into the ion beam. This allows the mass analyzer to start separating the ions based on the mass-to-charge ratio.[35]
