GC determination of fatty acids in green beans grown in Galicia (N.W. Spain)

Grasas y Aceites, 1996
The concentrations of lauric, myristic, palmitic, palmitoleic, stearic, oleic, linoleic, linolenic, arachidic acids in green beans (Phaseolus vulgaris L.) grown in Galicia (N.W. Spain) were determinated by capillary gas chromatography (GC). Palmitic acid

In Situ Synthesis of Hypercrosslinked Polymer as Stationary Phase for Capillary Gas Chromatography

Separations
Hypercrosslinked polymers (HCPs) constructed by the Friedel–Crafts alkylation reaction of aromatic compounds have emerged as a new class of porous materials with unique merit. Herein, a HCP named HCP-TPB was coated onto a capillary column through in situ

Identification of arachidonate epoxides/diols by capillary chromatography-mass spectrometry.

Journal of Lipid Research, 1995
The identification of epoxide regioisomers of arachidonic acid (EETs) as methyl esters is difficult because they coelute during gas chromatography and possess similar mass spectra.

Binder-jet printing and pressure-controlled infiltration for fabrication of high-temperature, low-dead-volume microfluidic interfaces

Additive Manufacturing Letters
Interfacing is a consistent weak point in the manufacturing of microscale gas chromatography columns. Current techniques for interfacing with microfluidic systems often degrade under high temperatures and thermal cycling and suffer from dead volumes.
