Notice of Intent To Update Existing Electron Ionization Mass 
Spectral Library

AGENCY: National Institute of Standards and Technology, Commerce.

ACTION: Notice and request for comments.

-----------------------------------------------------------------------

SUMMARY: The National Institute of Standards and Technology announces 
its intent to update its electron ionization mass spectral library. The 
update will increase the number of spectra from 130,000 to 
approximately 175,000. Interested parties are invited to submit 
comments to the address below.

DATES: Comments must be received by June 24, 2002.

ADDRESSES: Comments should be sent to the attention of Dr. Stephen 
Stein at the National Institute of Standards and Technology, Mail Stop 
8380, 100 Bureau Drive, Gaithersburg, MD, 20899-8520.

FOR FURTHER INFORMATION CONTACT: Dr. Stephen Stein by writing to the 
above address or by e-mail at [email protected] or by telephone at 
(301) 975-2444.

SUPPLEMENTARY INFORMATION: As part of its responsibilities under Title 
15 U.S.C. 290 to collect, evaluate and publish high quality Standard 
Reference Data (SRD), NIST creates and maintains evaluated SRD 
databases. One such database is the Mass Spectral Database which is an 
evaluated data collection containing electron ionization mass spectra 
for discrete chemical substances. The database is primarily used to aid 
in the identification of chemical compounds by providing a source for 
reference spectra for comparison to spectra acquired by commercial 
instruments, especially spectra generated by gas chromatography/mass 
spectrometry. For each spectrum, auxiliary information for chemical 
identification is provided, including chemical names, formulas, 
chemical structures and related information. The planned update will 
increase the number of spectra from 130,000 to approximately 175,000 
spectra, representing a wide variety of substances. The updated spectra 
will provide wider coverage of compounds and a higher level of 
accuracy. This will increase the confidence of users of the library in 
identifying chemical substances. We invite comments concerning this 
update

    Dated: May 20, 2002.
Karen H. Brown,
Deputy Director.
