Solid phase extractionis a common method for isolating and separating analytes from liquids. After passing through a cartridge, the analytes are adsorbed on the solid phase material, which has been preconditioned and activated with an organic solvent. The interferences are washed away while the analyt...
The use of supercritical fluid extraction (SFE) as an extraction technique is related to the unique properties of the supercritical fluid. These fluids have a low viscosity, high diffusion coefficients, low toxicity, and low flammability, all clearly superior to the organic solvents used in SPE ex...
Although we focused on experimental procedures for organic chemistry extracted from patents, the approach presented in this work is more general. It can be adapted to any extraction of operations from text, possibly requiring new training data or the definition of new action types to cover other d...
The definition of dietary fibers outlined by the American Association of Cereal Chemists [6] is that these compounds are “the remnants of the edible part of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine, with complete or partial ...
acetone, dimethyl ketone, propanone - the simplest ketone; a highly inflammable liquid widely used as an organic solvent and as material for making plastics chlorobenzene - a colorless volatile flammable liquid with an almond odor that is made from chlorine and benzene; used as a solvent and in...
Shale oil is not the same as fracking. Shale oil is an unconventional oil extracted from an organic-rich sedimentary rock (oil shale) by subjecting it to heat. Fracking or hydraulic fracturing, on the other hand, is the process of extracting tight oil using a high-pressure mixture of water...
Consistent with this definition, the presence of relatively small quantities of an equilibrium modifier will shift the extraction equilibrium slightly, resulting in minor diminution of aldoxime stripped solvent copper level at equilibrium, as will be reflected by a degree of modification value closely ...
Carbon nanomaterials (CNMs) have some excellent properties that make them ideal candidates as sorbents for solid-phase extraction (SPE). However, practical
