March 15, 2020
Author(s)
Lane C. Sander, Catherine A. Rimmer, Walter B. Wilson
Differences in the performance characteristics of seventeen commercial C30 liquid chromatographic columns were studied for the separation of carotenoid isomers. A mixture consisting of nine xanthophyll and hydrocarbon carotenoids were separated under

Calibration

October 2, 2019
Author(s)
Lane C. Sander
In the context of chemical metrology, calibration is the process of relating a known quantity of an analyte to the corresponding measured instrumental response through a mathematical relationship. Calibration permits the assignment of analyte levels in

Certification of Standard Reference Material 3389 Ginsenoside Calibration Solution

May 10, 2019
Author(s)
Walter B. Wilson, Lane C. Sander, Benjamin J. Place, James H. Yen
Standard Reference Material (SRM) 3389 is intended as a calibration solution for use for the determination of ginsenosides in natural matrix samples. A unit of SRM 3389 consists of two different ampule solutions: (1) four ampules of a six-component mixture

Development of a new reversed-phase liquid chromatography and fluorescence method with multichannel selective wavelength detection for the analysis of benzo[a]pyrene and six of its isomers

September 28, 2018
Author(s)
Walter B. Wilson, Stephen A. Wise, Lane C. Sander
The baseline separation of benzo[a]pyrene in complex samples via reversed-phase liquid chromatography (RPLC) is particularly challenging due to the potential for interferences from other molecular mass 252 (MM, g/mol) polycyclic aromatic hydrocarbons (PAHs

Determination of polycyclic aromatic hydrocarbons with molecular mass 302 in standard reference material 1597a by reversed-phase liquid chromatography and stop-flow fluorescence detection

June 21, 2018
Author(s)
Hugh Hayes, Walter Brent Wilson, Lane C. Sander, Stephen Wise, Andres Campiglia
The identification of isomeric polycyclic aromatic hydrocarbons (PAHs) in complex samples via reversed-phase liquid chromatography (RPLC) with fluorescence detection (FL) is normally based on matching the chromatographic retention times of suspected peaks

Normal-phase liquid chromatography retention behavior of polycyclic aromatic sulfur heterocycles (PASHs) and alkyl-substituted PASH isomers on an aminopropyl stationary phase
