“…These compounds, which are easily monitored by molecular ion mass fragmentography (m/z 184 + 14 , = 0-4), were also recently found by Bates and Carpenter (57) in extracts of Seattle's Metro wastewater effluent. On the basis of their complex homologies with dominant alkyl-substituted species (Figure 7), they are most likely derived from petroleum products (58,59).…”

Hydrocarbons isolated from southern California municipal wastewaters were analyzed by high-resolution gas chromatography and computer-assisted gas chromatography-mass spectrometry. Most of the hydrocarbons (56-77%) are not chromatographically resolvable and probably derive from petroleum products such as lubricating oils. Normal, iso-, and acyclic isoprenoid alkanes along with alkylcyclohexanes and numerous series of substituted benzenes and polycyclic aromatic hydrocarbons compose the major fraction of the resolvable hydrocarbons. Polycyclic terpenoids occur as trace constituents and appear also to be of ancient, not recent biosynthetic, origin.However, the virtual absence of 17 ( ),18 ( ),21ß( )-28,30-dinorhopane, a specific marker of California oils, indicates that locally produced petroleum is, at most, a minor contributor to these wastewaters. A homologous series of long-chain alkylbenzenes presumably derived from the LAS-type detergents was identified. These compounds seem to be abundant and ubiquitous domestic wastewater constituents that might be exploited as anthropogenic waste tracers in the marine environment.

“…The use of a sulfur-selective microcoulometric detector for the identification of one-, two-, three-, and four-ring thiophenic compounds in a variety of petroleum samples of different boiling point ranges has been reported (9,10). A Melpar flame photometric detector (FPD) with a 0003-2700/81/0353-0400$01.00/0 sulfur-selective filter has also been used to detect the presence of sulfur compounds in low concentrations in various crude oils (11) (although no identifications were given) and petroleum fractions (12). Clugston et al (13) used both microcoulometric and FPD sulfur-selective detection to identify the dominant sulfur compounds of a heavy oil and gas oil fraction from two bitumens to be alkyl-substituted benzo-and dibenzothiophenes with a limited number of isomers.…”

Sulfur heterocycles are found in low concentrations in most coalderived liquids and shale oils, and therefore, isolation of the heterocyclic sulfur fraction is necessary for individual compound Identification. In this report, a new methodology for the isolation and subsequent separation and identification of sulfur heterocycles is described and applied to selected coal liquids and shale oils. Identification was accomplished by sulfur-selective flame photometrk detection and comparison of mass spectral and chromatographic retention data of mixture components with standard reference compounds. Chromatographic retention data for 32 standard sulfur heterocycles were determined.

“…The thiophenic method was later improved using a flame photometric detector (FPD) (3). This detector is more sensitive and stable and gives more reproducible results than a microcoulometer.…”
