Pulsed discharge ionization detector: A pulsed discharge ionization detector (pulsed discharge detector) is a detector for gas chromatography that utilizes a stable, low powered, pulsed DC discharge in helium as an ionization source.Electron-capture mass spectrometry: Electron-capture mass spectrometry (EC-MS) is a type of mass spectrometry that uses electron capture ionization (ECI) to form negative ions from chemical compounds with positive electron affinities. The approach is particularly effective for electrophiles.Tris(1,3-dichloro-2-propyl)phosphateEssential oil: An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetherolea, or simply as the oil of the plant from which they were extracted, such as oil of clove.Gas chromatography–mass spectrometry: right|300 px|Example of a GC-MS instrument|thumbDodecaneCalibrationElectrospray ionizationPolychlorinated diphenyl ethers: Polychlorinated diphenyl ethers (PCDEs) are structurally similar to polychlorinated biphenyls (PCBs), both which may be toxic polyhalogenated compounds and some PCDE congeners have been reported to cause toxic responses similar to those caused by some of the non-ortho-substituted PCBs, which are mediated by the aryl hydrocarbon receptor (AhR).SetacJournals:ETHOXYRESORUFIN-O-DEETHYLASE INDUCTION POTENCY OF POLYCHLORINATED DIPHENYL ETHERS IN H4IIE RAT HEPATOMA CELLSGeneralizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.DibromomethaneAir ioniserSoft laser desorption: Soft laser desorption is laser desorption of large molecules that results in ionization without fragmentation. "Soft" in the context of ion formation means forming ions without breaking chemical bonds.
