High throughput screening of phenolic constituents in a complex sample matrix using post-column derivatisations employing reaction flow HPLC columns

Autor: Arianne Soliven, Agustín Acquaviva, R. Andrew Shalliker, Andrew Jones, Gary R. Dennis

Publikováno v: Microchemical Journal. 141:253-257

This communication is the first to demonstrate the high throughput power of a 30 mm in length reaction flow (RF) column to conduct a targeted analysis of phenolics in a complex sample matrix (tea) utilising post-column derivatisation (PCD). Sensitivi

Detection selectivity in the analysis of 'reactive' chemical compounds derived from natural samples via reaction flow chromatography

Autor: Arianne Soliven, Gary R. Dennis, Agustín Acquaviva, R. Andrew Shalliker, Andrew Jones

Publikováno v: Microchemical Journal. 139:315-321

The study of two commonly used post-column derivatisation (PCD) approaches for the selective detection of “bioactive” compounds in natural products were investigated – the ‘phenolic’ assay as the name suggests was responsive to phenolic com

Phenolic profiling of complex tea samples via simultaneous multiplexed detection employing reaction flow HPLC columns and colorimetric post column derivatisation

Autor: Arianne Soliven, Gary R. Dennis, Agustín Acquaviva, R. Andrew Shalliker, Andrew Jones

Publikováno v: Microchemical Journal. 138:533-539

A novel approach for the analysis of phenolics in tea was developed using multiplexed simultaneous detection. This is the first study employing a short reaction flow (RF) chromatography column (length 50 mm) for the analysis of phenolics in complex s

High throughput method to characterize acid-base properties of insoluble drug candidates in water

Autor: Cecilia B. Castells, Damián Ezequiel Benito, Agustín Acquaviva, Leonardo Gabriel Gagliardi

Publikováno v: Journal of Pharmaceutical and Biomedical Analysis. 154:404-412

In drug design experimental characterization of acidic groups in candidate molecules is one of the more important steps prior to the in-vivo studies. Potentiometry combined with Yasuda-Shedlovsky extrapolation is one of the more important strategy to

Chiral x achiral multidimensional liquid chromatography. Application to the enantioseparation of dintitrophenyl amino acids in honey samples and their fingerprint classification

Autor: Agustín Acquaviva, Marcelo R. Filgueira, Cecilia B. Castells, Gabriel G. Siano, Pamela Yanina Quintas

Publikováno v: Journal of chromatography. A. 1614

Most HPLC enantiomer separations are performed with columns packed with a chiral stationary phase (CSP) operated with an achiral mobile phase. The intrinsically limited chemical selectivity of most CSPs to the simultaneous resolution of several pairs
