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 Wilson, Lane 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

December 14, 2017
Author(s)
Walter Wilson, Hugh Hayes, Lane Sander, Andres Campiglia, Stephen Wise
Retention indices for 67 polycyclic aromatic sulfur heterocycles (PASHs) and 80 alkyl- substituted PASHs were determined using normal-phase liquid chromatography (NPLC) on a aminopropyl (NH2) stationary phase. The retention behavior of PASH on the NH2

Gas Chromatographic Retention Behavior of Polycyclic Aromatic Hydrocarbons (PAHs) and Alkyl- Substituted PAHs on Two Stationary Phases of Different Selectivity

November 8, 2017
Author(s)
Federica Nalin, Lane C. Sander, Walter B. Wilson, Stephen A. Wise
Retention indices (RIs) for 45 polycyclic aromatic hydrocarbons (PAHs) and 63 methyl- substituted PAHs were determined by gas chromatography – mass spectrometry (GC-MS) using two different stationary phases: a 50% (mole fraction) phenyl-substituted

Development of a Cigarette Tobacco Filler Standard Reference Material

September 20, 2017
Author(s)
Lane C. Sander, Jeanita Pritchett, Laura J. Wood, Brian Lang, Stephen Wise, Matt J. Walters, T. Phillips, M. J. Holman, G. Lee, J. Lisko, B. Lane, L. Valentin, B. Kimbrell, S. Kuklenyik, S. Stanfill, C. Watson
A new tobacco filler Standard Reference Material (SRM) has been issued by the National Institute of Standards and Technology (NIST) in September 2016 with certified and reference mass fraction values for nicotine, N-nitrosonornicotine (NNN), 4-

Development of Standard Reference Material (SRM) 2973 Vitamin D Metabolites in Frozen Human Serum (High Level)

July 24, 2017
Author(s)
Susan Tai, Michael Nelson, Brian Lang, Karen W. Phinney, Lane C. Sander, James H. Yen, J. M. Betz, Christopher T. Sempos, Stephen Wise
The National Institute of Standards and Technology (NIST), in collaboration with the National Institutes of Health, Office of Dietary Supplements (NIH-ODS) and the Vitamin D Standardization Program (VDSP), has recently issued a new serum-matrix Standard

Qualitative characterization of SRM 1597a Coal Tar for polycyclic aromatic hydrocarbons and methyl-substituted derivatives via normal-phase liquid chromatography and gas chromatography/mass spectrometry

June 29, 2017
Author(s)
Walter Wilson, Hugh Hayes, Lane Sander, Andres Campiglia, Stephen Wise
A normal-phase liquid chromatography (NPLC) fractionation procedure was developed for the characterization of a complex mixture of polycyclic aromatic hydrocarbons (PAHs) from a coal tar sample (Standard Reference Material (SRM) 1597a). Using a semi
