Classification and treatment of errors in reference mass spectra

February 27, 1994
Author(s)
Anzor I. Mikaia, S G. Lias, Stephen E. Stein
Requirements to reference spectra and criteria for mass spectrum inclusion, modification and deletion are developed as a result of evaluation of thousands of spectra and analysis of encountered errors. Errors due to a sample, device and operator, data

The control of quality in a comprehensive mass spectral library

May 30, 1993
Author(s)
Anzor I. Mikaia, S G. Lias, Stephen E. Stein
Computer generated "Quality Index" for the selection of spectra for the inclusion to the NIST/EPA/NIH mass spectral library is abandoned. We have undertaken a program to manually examine all spectra in the database. Suspect spectra are first examined to

Mass spectrometry of derivatives and heterocyclic analogues of 9,10-dihydroanthracene

January 1, 1991
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin, Alexey V. Varlamov, Nikolay A. Prostakov
Fragmentation of derivatives of 9,10-dihydroanthracene and of its heterocyclic analogues containing atoms of O, S, N, P, Si, As, Se and Te at positions 9 and/or 10 is examined. The conditions reviewed are electron impact and chemical ionization in positive

A method for the synthesis of N-alkylpiperidynes.

June 27, 1990
Author(s)
Anzor I. Mikaia, George A. Kliger, OA Lesik, EV Marchevskaya, Vladimir G. Zaikin, Leonid S. Glebov, Sergai Loktev
Reaction gas chromatography–mass spectrometry is applied to establish optimal conditions for the synthesis of N-alkylpiperidynes. Further optimization of the reaction was carried out in a pilot plant.
