This book contains the electron capture negative ion (ECNI) mass spectra of 361 compounds that are of general environmental interest, including halogenated benzenes and phenols, nitroaromatic hydrocarbons, polycyclic aromatic hydrocarbons, DDT derivatives, diene pesticides, halogenated biphenyls, dioxins, and dibenzofurans. All spectra have been measured in the author's laboratory. Two are reported for each compound using ion-source temperatures of 100 and 250{degrees}C and an ion-source pressure of . Torr methane.

The intensity of molecular ions increased with the number of chlorine atoms present, but this was counteracted by enhanced fragmentation as the number of ortho position chlorine atoms increased. Stemmler, E.

Differences in the electron capture negative ion mass spectra of environmentally related organic compounds acquired on a VG 30-250 triple quadruple mass spectrometer and on an HP 5985B ga. .

Differences in the electron capture negative ion mass spectra of environmentally related organic compounds acquired on a VG 30-250 triple quadruple mass spectrometer and on an HP 5985B gas chromatography/mass spectrometry system were investigated with respect to the ion formation process. Neither ion source temperature nor pressure was responsible for the differences.

Electron capture ionization is the ionization of a gas phase atom or molecule by attachment of an electron to create an ion of the form A. The reaction is. where the M over the arrow denotes that to conserve energy and momentum a third body is requir. where the M over the arrow denotes that to conserve energy and momentum a third body is required (the molecularity of the reaction is three). Electron capture can be used in conjunction with chemical ionization.

This book contains the ECNI mass spectra of 361 compounds selected to include the major classes of environmental con- taminants, such as those found on the U.S. Environmental Protection Agency's priority pollutant list. Compound clas- ses of environmental importance include halogenated benzenes and phenols, nitrobenzenes and the related dinitro herbicides, polycyclic aromatic hydrocarbons, DDT derivatives, hexachloro- cyclopentadiene pesticides, halogenated biphenyls, dioxins, and dibenzofurans. The spectra, measured with the ion source at 100 oC and 250 oC, are reported graphically. In addition, compound name, Chemical Abstracts registry number, molecular weight, and structure are given. This collection of reference spectra will be of use to environmental scientists and to analytical chemists concerned with the sensitive detection and identification of synthetic chemicals in a wide variety of matrices.
