Quenched phosphorescence detection in cyclodextrin-based electrokinetic chromatography.

Analytical chemistry

Kuijt J, Roman DA, Ariese F, Brinkman UA, Gooijer C.
PMID: 12380841
Anal Chem. 2002 Oct 01;74(19):5139-45. doi: 10.1021/ac020270v.

Quenched phosphorescence detection is a sensitive detection method recently introduced in capillary zone electrophoresis. It is based on the dynamic quenching interaction of the analytes (quenchers) with a phosphorophore, 1-bromo-4-naphthalenesulfonate (BrNS), present in the separation buffer. In this study,...

Seasonal variation of polycyclic aromatic hydrocarbon metabolites in bile of white perch Morone americana from two Chesapeake Bay tributaries.

Diseases of aquatic organisms

Matsche MA, Pulster EL.
PMID: 34854819
Dis Aquat Organ. 2021 Dec 02;147:63-86. doi: 10.3354/dao03637.

Polycyclic aromatic hydrocarbon (PAH) accumulation in the bile is a reliable biomarker of recent exposure to environmental PAH and elevated concentrations have been identified as significant risk factors for hepatic disease in some fish species. Recent surveys (spring 2019)...

Combination of "Buttressing" and "Clothespin" Effects for Reaching the Shortest NHN Hydrogen Bond in Proton Sponge Cations.

A series of previously unknown 2,4,5-tri- and 2,4,5,7-tetrasubstituted 1,8-bis(dimethylamino)naphthalenes and their salts with HBF

Polychlorinated naphthalenes in farmed Chinese mitten crabs in China: Concentration, distribution and source analysis.

Environmental research

Wang Y, Zhang S, Fan M, Wang R, Zou Y, Wang P, Cheng J, Dong S.
PMID: 34929190
Environ Res. 2021 Dec 18;206:112582. doi: 10.1016/j.envres.2021.112582. Epub 2021 Dec 18.

Polychlorinated naphthalenes (PCNs) are both highly toxic and bioaccumulative environmental contaminates. Dietary intake is the primary pathway for human exposure to PCNs, and PCN concentrations in aquatic foodstuffs are relatively high. Chinese mitten crab (Eriocheir sinensis) is one kind...

Self-Assembly of a Pyridine-Based Amphiphile Complexed with Regioisomeric Dihydroxy Naphthalenes into Supramolecular Nanotubes with Different Inner Diameters.

Chemistry (Weinheim an der Bergstrasse, Germany)

Chemistry. 2021 Sep 01;27(49):12566-12573. doi: 10.1002/chem.202101354. Epub 2021 Aug 04.

A pyridine-based amphiphile complexed with 1,5-, 1,6-, 2,6-, or 2,7-dihydroxy naphthalene self-assembled in water to form nanotubes with inner diameters of 46, 38, 24, 18, and 11 nm in which the naphthalene molecules formed J-type aggregates. In contrast, the...

Investigation of partition coefficients and fingerprints of atmospheric gas- and particle-phase intermediate volatility and semi-volatile organic compounds using pixel-based approaches.

Ambient gas- and particle-phase intermediate volatility and semi-volatile organic compounds (I/SVOCs) of Beijing were analyzed by a thermal desorption comprehensive two-dimensional gas chromatography quadrupole mass spectrometry (TD-GC × GC-qMS). A pixel-based scheme combing the integration-based approach was applied for...
