TL;DR: These results indicate that environmental endocrine-disrupting estrogens are not completely removed in the process of sewage treatment but are carried over into the general aquatic environment.
Abstract: A method for the analysis of phenolic estrogenic active compounds in surface and drinking water in the picogram per liter range is described. Besides the widely used monomer bisphenol A, 4-tert-octylphenol [4-(1,1,3,3-tetramethylbutyl)phenol] and the technical isomer mixture of 4-nonylphenol; phenolic steroid hormones such as the endogenous estrogens estrone, 17α-estradiol, and 17β-estradiol; and the exogenous estrogen 17α-ethinylestradiol were determined in water at the 20−200 pg/L level. Water samples from 1 to 5 L were extracted by solid-phase extraction (SPE) on a cartridge system containing LiChrolut EN as sorbent. The phenols and steroids were converted into their pentafluorobenzoylate esters in an extractive derivatization reaction. The derivatives were then determined by high-resolution gas chromatography with negative chemical ionization mass spectrometric detection (HRGC−(NCI)−MS) in the selected ion mode (SIM). All results were also confirmed by HRGC with electron capture detection (ECD). This ...

TL;DR: A simple dispersive liquid-liquid microextraction method based on solidification of a floating organic drop (DLLME-SFO) technique combined with gas chromatography/electron-capture detection (GC/ECD) or gas Chromatography/mass spectrometry ( GC/MS) has been developed and overcomes the most important problem in DLLME, the high-toxic solvent used.

TL;DR: In this paper, a gas chromatograph (GC) equipped with Hydrogen Flame Ionization Detector and Electron Capture Detector (ECD) can measure CH4, CO2, and N2O simultaneously in an air sample in four minutes.
Abstract: Combining improved injector, gas line and valve-driving models, a gas chromatograph (GC) equipped with Hydrogen Flame Ionization Detector (FID) and Electron Capture Detector (ECD), can measure CH4, CO2, and N2O simultaneously in an air sample in four minutes. Test results show that the system has high sensitivity, resolution, and precision; the linear response range of the system meets the requirement of flux measurements in situ. The system is suitable for monitoring fluxes of the main greenhouse gases in a short-plant field since it is easy to use, efficacious, and constant and reliable in collecting data.

TL;DR: The GC-ECD and HPLC-UV concentration estimates of explosives residues in field-contaminated soils from hazardous waste sites were compared, and correlation was excellent between the two methods of analysis for each of the compounds most frequently detected.
