Wiley Registry ofMass Spectral Data 2023
From the Leader in Spectral Data

The essential GC-MS library for
confident spectral analysis
The field-tested and proven Wiley Registry of Mass Spectral Data
continues to empower laboratories worldwide. The 2023 release ofthis vital MS database provides access to over 873,000 spectra withexpanded coverage to expedite your workflow even further.
Designed for use across multiple applications, from untargeted
GC-MS screening to accurate mass workflows with MS-TOF
instruments, this collection ensures confidence in your spectral
search results, even in the most in demanding applications.
•Broad range of compounds for targeted and non-targeted
analyses—increase both the speed and likelihood ofidentification with a comprehensive dataset.

•Spectral records contain additional information that’s
searchable such as physical properties, structures, and DOIs
when available to help narrow your results even further.

•Data is carefully curated and reviewed by Wiley’s internaland external experts to ensure it meets quality standards forresults you can rely on.

•Spectra are segmented into separate libraries includingexcess replicate spectra to enable robust searching across variedlaboratory settings.

•Take the guesswork out of instrument compatibility. Wiley
Registry is available in the most common manufacturer formats.

Increase the speed
and likelihood of MS
identification withexpanded coveragein the latest releaseof this trusted
resource.

And with our new subscription option you get access to even more
spectral data as it’s added to the collection between releases!

A foundational tool for any laboratory engaged in GC-MS analysis, this spectral
library remains a lab standard, consistently evolving to meet the ever-growing
research demands of today in our continued commitment to deliver relevant, quality
data.
Available in the most common instrumentation manufacturer formats, this spectral libraryis a necessity for any laboratory engaged in GC-MS analysis.

Be sure your lab is up to date with the latest release of this evolving collection. Take
advantage of all the benefits in the 2023 release:•Addition of over 50,000 unique compounds with over 56,000 spectra.

•Expanded coverage of world patents and peer reviewed literature, including
DOIs of source articles. Data is also sourced from partner labs.

•All spectra have been assigned a quality index, enabling searches to be tuned toexclude spectra below a quality index threshold.

APPLICATIONSThis collection oﬀers exceptional reliability as a comprehensive resource for theanalysis, identification, classification, and verification of compounds by mass
spectrometry in a wide range of applications such as environmental, forensics/
toxicology, metabolomics, pharmaceutical, biotech, food/cosmetics, defense/
homeland security, and many more.

ADDITIONAL INFORMATION
When it comes to spectral analysis, the more data you have the better. Wiley spectral
databases provide much more information than simply the spectrum to give you afuller picture of your results. Database records may include valuable details whenavailable for a record such as:••••••

Chemical Structure
Chemical Name
Exact Mass
Calculated Kovats RI values
Splash IDs
Wiley ID•••••

FormulaInChI/InChIKey
Molecular Weight
Quality Index (QI)
Digital Object Identifier (DOI)

And because it’s searchable, you can use this information to narrow your results evenfurther.

ABOUT THE AUTHORS
Originating through a collaboration by Drs. Einar August Stenhagen, Fred McLaﬀerty,
and Sixten Abrahamsson, the Wiley Registry pioneered the use of spectral data inmass spectrometry.
•••

Sixten Abrahamsson, a member of the Royal Swedish Academy of Sciences,
was an x-ray crystallographer whose group studied structure and function of
biologically active molecules.
Fred McLaﬀerty, a member of the National Academy of Sciences, was a leading
light in mass spectrometry, known for top-down analysis and the McLaﬀerty
rearrangement.
Einar Stenhagen, a member of the Royal Swedish Academy of Sciences,invented, with his wife, Stina Ställberg-Stenhagen, the jet separator, enabling thecombination of gas and liquid chromatography with mass spectrometry.

Since 2009, the Wiley Registry has been maintained and updated by the Wiley ScienceSolutions data team.
