Agustín Acquaviva, Andrew Jones, Gary R. Dennis, Cecilia Castells, more

Microchemical Journal > 2018 > 142 > C > 181-186

This study highlights the capability to conduct a post column derivatisation (PCD) process with a narrow bore, low volume column. A reaction flow (RF) HPLC column (30 mm × 2.1 mm internal diameter (i.d.), 3 μm particle diameter) enabled the selective detection of phenols for both a simple standard mixture and a complex sample represented by green tea. The resolving power and sensitivity obtained were...

A simplified guide for charged aerosol detection of non-chromophoric compounds—Analytical method development and validation for the HPLC assay of aerosol particle size distribution for amikacin

Arianne Soliven, Imad A. Haidar Ahmad, James Tam, Nani Kadrichu, more

Journal of Pharmaceutical and Biomedical Analysis > 2017 > 143 > C > 68-76

Amikacin, an aminoglycoside antibiotic lacking a UV chromophore, was developed into a drug product for delivery by inhalation. A robust method for amikacin assay analysis and aerosol particle size distribution (aPSD) determination, with comparable performance to the conventional UV detector was developed using a charged aerosol detector (CAD). The CAD approach involved more parameters for optimization...

Industrial Crops and Products > 2017 > 100 > C > 77-84

Kernels recovered from fruit pits (industrial by-products) of twenty-eight plum varieties of two species Prunus domestica L. and Prunus cerasifera Ehrh. were studied as potential biodiesel feedstock. The lowest (22.7% (w/w) on dry weight basis (dw)) and the highest (53.2% (w/w) dw) oil yields in the tested varieties differed by almost two-fold. The levels of oleic and linoleic acids, the two dominant...

Improving the performance of narrow-bore HPLC columns using active flow technology

Arianne Soliven, Dominic Foley, Luisa Pereira, Stanly Hua, more

Microchemical Journal > 2014 > 116 > Complete > 230-234

Active flow technology (AFT) columns are designed to remove inefficient flow processes associated with the column wall and radial heterogeneity. This study is the first to explore AFT on a 2.1mm internal diameter (i.d.) column, emulating a 1.0mm i.d. column. The performance of the AFT column was compared to a conventional 1.0mm i.d. column; at the highest linear velocities tested it was observed that...

Journal of Separation Science > 37 > 15 > 1937 - 1943

The synthesis and chromatographic behavior of an analytical size mixed‐mode bonded silica monolith was investigated. The monolith was functionalized by an in situ modification process of a bare silica rod with chloro(3‐cyanopropyl)dimethyl silane and chlorodimethyl propyl phenyl silane solutions. These ligands were selected in order to combine both resonance and nonresonance π‐type bonding within...

The Development of the In Situ Modification of 1st Generation Analytical Scale Silica Monoliths

Arianne Soliven, Gary R. Dennis, Emily F. Hilder, R. Andrew Shalliker, more

Chromatographia > 2014 > 77 > 9-10 > 663-671

Analytical scale silica monoliths are commercially limited to three column selectivities (bare silica, C8 and C18). An in situ modification is reported in detail to overcome this barrier and allow for any functionality of choice to be bonded to the silica surface of the monolithic stationary phase support. The modification method was conducted on a commercial bare silica column to bond the C18 moiety...
