Evolution of the NIST Library

nist-library-historyThe tools that scientists need to do their jobs are constantly evolving, and the NIST library is no exception. The most widely used mass spectral reference library is frequently updated with new information that makes it easier than ever for scientists to efficiently and accurately complete their research. Here are some reasons why you should consider upgrading or purchasing the latest NIST library.

More spectra than ever

Today’s NIST library, NIST 14, is much more robust than previous versions. Since the NIST 02 version, the library has expanded to now contain 276,248 El spectra, including 242,466 unique spectra. The library also includes an MS/MS Library that contains 234,284 spectra – 51,216 ion trap spectra for 42,126 different ions of 8,171 compounds, and 183,068 collision cell spectra (qtof and tandem quad) for 14,835 different ions of 7,692 compounds.

An improved retention index

The size of the retention index in NIST 14 has also increased considerably. The original version of the library actually didn’t have retention index data. When the index finally was added, it contained 121,112 index values for 25,893 compounds. Now, however, the library’s retention index contains 387,463 index values for 82,868 compounds, a significant improvement.

Search and AMDIS software enhancements

Since the 02 version, the library has also improved its search and AMDIS software. The NIST MS Search software has been updated for identifying compounds from mass spectra and for browsing the mass spectral library.

The library also includes MS interpretation programs to analyze mass spectra on the basis of chemical structure, molecular formulas, isotopic patterns, and more. In addition, updates have been made to AMDIS software used for deconvoluting gas/liquid chromatograms.

Other updates

Other updated components of the NIST library include the following:

  • Electron ionization mass spectral library – 276,259 spectra of 242,477 unique compounds
  • Gas chromatography data library – 385,872 retention index values for 82,337 compounds
  • Documentation – A 50-page printed and electronic manual on setup and basic usage

With each update the library has improved, making it possible to more accurately identify compounds. Many of the updates actually come from NIST library users. If a lab tests a compound and finds a new spectrum, it can notify the National Institute of Standards and Technology, which will then examine the data and determine if it needs to update the library.

The latest features

The latest version, NIST 14, comes with additional tools and enhanced features, including the ability to search for exact mass—critical for research involving high-resolution mass spectrometry—and more powerful retention index tools, which are essential for determining the identity of unknowns when secondary confirmation is required.

The upgrade also comes with new definitions of derivatives used for finding replicate spectra, and a new MS/MS search for small molecules, including more robust scoring for spectra acquired on imperfectly tuned instruments.

Having the latest data to accurately identify compounds is vital for anyone working in mass spectrometry. NIST 14 gives scientists the most up-to-date spectra, providing them with confidence that they have data they can trust. This not only makes their job easier, it also helps to protect against inaccuracies and potential legal issues.

What You Need to Know About NIST

nist-libraryDid you know that measurement services provided by the National Institute of Standards and Technology (NIST) support over 10 million medical procedures, including prostate and breast cancer treatments, enhancing their safety and effectiveness? Or that 10 to 15 percent of the more than $2 trillion the U.S. spends annually on health care is associated with NIST’s measurements?

Millions of scientists and technologists rely on NIST for the technology, measurements, and standards it provides. Founded in 1901 as an agency of the U.S. Department of Commerce, NIST operates from locations in Gaithersburg, Maryland, and Boulder, Colorado, with activities organized into laboratory and extramural programs.

What NIST does

NIST’s mission is simple: to promote U.S. innovation by advancing measurement science, standards, and technology in ways that will enhance the economy and improve quality of life.

NIST aims to fulfill its mission through various projects, including:

  • Providing measurements and standards for industries, academia, and the government, with over 1,300 standard reference materials. These artifacts are certified as having specific characteristics and are used for measuring equipment and procedures, quality control benchmarks, and experimental control samples.
  • Publishing “Handbook 44” each year to provide uniform specifications for weighing and measuring devices
  • Providing homeland security assistance, such as identification card standards for federal employees and contractors
  • Conducting investigations, including one into the collapse of the World Trade Center buildings
  • Working with various committees on voting system guidelines and voting machines

Most of the technology we use on a daily basis is dependent on NIST programs. For example, NIST’s accurate time measurement capabilities enable U.S. cell towers to be synchronized to one millionth of a second every day. Also, NIST’s work on the development of encryption standards is estimated to have saved private industry more than $1 billion and improved the security of ATM withdrawals and billions of dollars’ worth of daily electronic data transactions.

The NIST mass spectral library

As many scientists may know, NIST also supports the NIST mass spectral library, the most widely used and trusted resource for identifying mass spectra. The NIST mass spectral library is a compilation of tools and peer-reviewed databases and includes the full-featured NIST MS Search Program and other spectral analysis utilities, including the NIST Automated MS Deconvolution and Identification System (AMDIS) and MS Interpreter.

The databases contain spectra, structures, and extensive reference data from a number of sources, including contributors, compounds measured at NIST, and spectra extracted from the literature.

The library is constantly updated (currently version 14) and with every release, spectra are examined for their accuracy. The latest library upgrades added the ability to search for exact mass, expanded the variety of precursor ions for tandem mass spectra, and integrated retention index and mass spectral data.

Why Get Your NIST Mass Spectral Library from Us?

nist-mass-spectral-library-why-buyWhen shopping for critical research tools, or anything for that matter, it makes no sense to pay more than you have to. This is especially true when it comes to interpreting mass spectra results. There’s only one current NIST Mass Spectral Library (NIST 14), but many outlets where you can purchase the database and software.

Here are four solid reasons why our NIST 14 is your best choice.

No Bricks and Mortar

One of the advantages of Internet stores is that they exist solely online. When it comes to overhead, that represents a significant savings, both for us and for you. No building maintenance (which includes everything from repainting exteriors to paying a security company to monitor the property), no janitorial service fees, no water and sewer bills, no store furniture to purchase … the list goes on and on. By minimizing our cost of operations, we’re able to offer our clients a better value.

No Inventory

Another source of significant savings is that we hold no inventory. We only burn a copy of the NIST Mass Spectral Library when you order it.

It’s much more efficient for us to burn and test each copy “on demand” rather than ship out production to an anonymous DVD press for burning alongside, say, “Jane Smith’s” newest yoga class. And because we have no inventory, we don’t have to buy shelves, fancy displays, or warehouse storage space, resulting in lower costs for our customers.

No Shipping Costs

We don’t charge you for shipping NIST 14. We cover the cost because we’ve learned that U.S. Postal Service priority shipping works extremely well, without the high fees of some more courier-focused companies. Our savings is your savings.

No Sacrifice of Customer Service

Of course, there are some companies out there selling the NIST Mass Spectral Library for less money than we do, but there’s a reason for that: They cut corners with their customer service. This is where we stand head and shoulders above our competitors.

Instead of investing in facilities or inventory, we’ve chosen to invest in human intelligence. We offer a technical support department with high levels of academic experience who are available—and even eager—to answer your questions. They helped develop the NIST Mass Spectral Library and know it inside and out. We’ve retained this level of expertise in order to be absolutely certain we can answer any technical or installation questions you may have.

We are confident you will get the best value possible when you purchase the NIST Mass Spectral Library from us.
