High pressure liquid chromatography of benzimidazolcs

open access: yesPesticide Science, 1976
AbstractA laboratory‐assembled high pressure liquid chromatograph with variable wavelength ultraviolet detector is described. The chromatography of the systemic fungicides benomyl, thiabendazole, thiophanate, related fungicides and benzimidazoles (13 compounds in all) is described using reverse phase and adsorption systems.

Equation of state of liquid Indium under high pressure

open access: yesAIP Advances, 2015
We apply an equation of state of a power law form to liquid Indium to study its thermodynamic properties under high temperature and high pressure. Molar volume of molten indium is calculated along the isothermal line at 710K within good precision as ...

New Metabolites of Coumarin Detected in Human Urine Using Ultra Performance Liquid Chromatography/Quadrupole-Time-of-Flight Tandem Mass Spectrometry

open access: yesMolecules, 2017
Coumarin (1,2-benzopyrone) is a natural compound whose metabolism in humans was established in the 1970s. However, a new metabolite was recently identified in human plasma, indicating that the metabolism of coumarin has not been completely elucidated. To

Glass–liquid transition of water at high pressure [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
The knowledge of the existence of liquid water under extreme conditions and its concomitant properties are important in many fields of science. Glassy water has previously been prepared by hyperquenching micron-sized droplets of liquid water and vapor deposition on a cold substrate (ASW), and its transformation to an ultraviscous ...
