Mass Wiley Registry

Mass Spectral Library[35] and the Wiley Registry of Mass Spectral Data[36] are now available to help mass spectrometrists in the identification of unknowns.

Today, GC-MS (see Section 4.1.1) is a golden standard for detection and quantification of drugs and poisons volatile under GC conditions, whereas nonvolatile compounds require LC-MS (see Section 4.1.2). The GC-MS technique is much more popular for identification purposes than LC-MS, because of the easy availability of the reference mass spectra for many xenobiotics and their derivatives, either in printed or computer form. The most popular libraries are the NIST library, which contains the mass spectra of 130,000 compounds, the Wiley Registry of Mass Spectral Data, which contains 390,000 reference spectra, and the Pfleger-Maurer-Weber library, with 6,300 mass spectra and other data, such as chromatographic retention indexes.

McLafferty and Stauffer published in The Wiley Registry of Mass Spectral Data a collection of about 380000 spectra of over 200000 compounds [3]. It is the largest and most comprehensive library of reference spectra that contains over 180000 searchable structures and over 2 million chemical names. The eighth edition of The Wiley Registry of Mass Spectral Data is available in electronic format and is compatible with the software of most instrument manufacturers and NIST MSSearch. Furthermore, it is accompanied by an interpretation help program called Probability Based Matching (PBM). 

The Wiley Registry of Mass Spectral Data, the most comprehensive library of mass spectral data. The 7lh edition contains over 338,000 El mass spectra. It is marketed by John Wiley Sons and Pahsade Corporation. 

Combined GC-MS is the standard technique used for identifying cuticular waxes, and electron ionization (El) is the most widely used MS ionization technique in their analysis. The most frequent and simple method of identification involves comparison of the recorded mass spectra with those in standard mass spectral libraries or with those of authentic standards. Unfortunately, the spectra of wax constituents are rarely published in MS libraries (e.g. NIST Chemistiy WebBook, Wiley Registry of Mass Spectral Data, MSDC). For compounds that remain unidentified in the above MS libraries, the mass sp>ectra found in the literature can be consulted. Table 2 gives the references of published mass spectra or fragmentation patterns for some less common cuticular wax components. 

The great majority of today s GC-MS applications ntiUze one-dimensional capillary GC with quadrupole MS detection and electron ionization. Nevertheless, there are snbstantial numbers of applications using different types of mass spectrometers and ionization techniqnes. The proliferation of GC-MS applications is also a result of conunercially available easy-to-handle dedicated mass spectral libraries (e.g., NIST/EPA/NIH 2005 WILEY Registry 2006 MassFinder 2007 and diverse printed versions such as Jennings and Shibamoto, 1980 Joulain and Konig, 1998 and Adams, 1989, 1995, 2007 inclusive of retention indices) providing identification of the separated componnds. However, this type of identification has the potential of prodndng some unreliable resnlts, if no additional information is used, since some compounds, for example, the sesquiterpene... 

The Wiley Registry of Mass Spectral Data has been published in its 10th Edition (John Wiley Sons, 2013, Editor Fred W. McLafferty) (McLafferty and Stauffer, 1989). It is the largest and most comprehensive mass spectral library ever made commercially available in the most common mass spectrometry software formats and compatible with most manufacturer data systems. Applications include pathology, toxicology, forensics, quality assurance, border control, research and development, food safety and environmental sciences. The 10th edition of the Wiley Registry contains ... 

Also available is the combination of the large Wiley Registry with the current NIST database. The Wiley Registry 10th Edition/NIST 2012 (W10/N12, ISBN 978-1-118-61611-6 of June 2013) provides today the most extensive mass spectral hbrary with ...
