Gas chromatography- definition, principle, working, uses
Jul 11, 2020Gas chromatography differs from other forms of chromatography in that the mobile phase is a gas and the components are separated as vapors.; It is thus used to separate and detect small molecular weight compounds in the gas phase. The sample is either a gas or a liquid that is vaporized in the injection port.
LCGC Europe – Flying High with Sensitivity and Selectivity
Capillary gas chromatography coupled to mass spectrometry (GC–MS) is a straightforward, yet powerful, coupling of the selectivity of GC with the high sensitivity and option of universal or selective detection of MS. Traditional GC–MS provides multiple dimensions of separations and low detection limits in benchtop or smaller instruments.
Methods of physical separation | Separating mixtures
Chapter overview. 2 weeks 'Mixtures' was first introduced in Gr. 6, so learners should already be familiar with these concepts. Learners would have also looked at some of the physical methods of separating different types of mixtures (including hand sorting, sieving, filtration), and this year we will explore some additional methods in more detail (including distillation and chromatography).
Shape-Memory Polymer Nanocomposites of Poly(ε-caprolactone
Feb 22, 2021Shape-memory polymer composite (SMPC) blends with thermo-responsive shape memorizing capability have received increasing interest and have been a grooming research area due to their various potential applications. In this work, we report three thermo-responsive SMPCs derived from poly(ε-caprolactone) (PCL) and the polystyrene-block-polybutadiene-block-polystyrene-tri-block

Hydrogen Evolution Reaction - an overview | ScienceDirect
J. Yang, C. Yang, in Membrane Reactors for Energy Applications and Basic Chemical Production, 2015 Bubble formation control. Hydrogen evolution reactions are always accompanied by the electrochemical desulfurization process. Although mass transport leads to greater reaction rates, the large number of gas bubbles formed, resulting from the increased reaction rate, can adversely hinder the
