This paper describes a novel improved hydrocarbon recovery (IHR) screening methodology
capable of (1) screening and prioritizing a large number of reservoirs for various IHR …

As part of an ongoing research program on authentication, safety and biological evaluation
of phytochemicals and dietary supplements, an in-depth chemical investigation of different …

This study evaluated the use of a new concurrent backflushing set-up in the multiresidue
analysis of pesticides in dietary supplement matrices using gas chromatography–tandem mass …

The analysis of fatty acid methyl esters is a very important application in food analysis. Fatty
acid methyl esters are normally analyzed on columns coated with polar stationary phases …

For the first time in the literature, application of a GC-ICP-MS/MS method for the selective
and sensitive detection of specific heteroatoms of phosphorus, sulfur, and chlorine has been …

Methoxypyrazines are volatile compounds found in plants, microbes, and insects that have
potent vegetal and earthy aromas. With sensory detection thresholds in the low ng L −1 range…

… Although the yields were not optimized, they are sufficiently high that the method compares
favorably with othermethods reported for the synthesis of cyclophanes l(ioa-c,22,25 2,11.19-…

For efficiency in a regulatory setting, multiresidue methods (MRMs) are preferred to single-residue
methods (SRMs) for the analysis of pesticides in agricultural products, since many …

Oil can become bypassed during gas injection as a result of gravitational, viscous, and
heterogeneity effects. Mass transfer from the bypassed region to the flowing gas is dependent …

A full-scan GC/quadrupole/MS method has been developed to perform large-scale screenings
of pesticides and simultaneous quantification of 95 target compounds in a single run of 21 …
