Poly(amidoamine)s synthesis, characterisation and interaction with BSA [PDF]

, 2014
Cationic poly(amidoamine)s (PAAs) were synthesised and characterised by NMR and gel permeation chromatography. Their thermal properties were investigated using thermogravimetric analysis and differential scanning calorimetry.

Determination of Dioxins and Dioxin-like Polychlorinated Biphenyls in Pork by Gas Chromatography-Tandem Mass Spectrometry [PDF]

Shipin Kexue, 2023
A gas chromatography-tandem mass spectrometry (GC-MS/MS) with stable isotope dilution (SID) method was established for the determination of dioxins (PCDD/Fs) and dioxin like polychlorinated biphenyls (DL-PCBs) in pork. The sample was extracted by Soxhlet

Quantitative ultraviolet measurements on wetted thin-layer chromatography plates using a charge-coupled device camera [PDF]

, 2008
This paper presents the first study of the UV imaging of spots on thin-layer chromatographic plates whilst still wet with solvent. Imaging of spots of benzophenone during and after development was carried out using a charge-coupled device camera.

Oxalate-silica gel thin-layer system for free 2-hydroxy fatty acids and for fatty acyl coenzyme A

Journal of Lipid Research, 1972
The 2-hydroxy fatty acids tend to yield streaks in thin-layer chromatography on silica gel plates. If potassium oxalate is included with binder-free silica gel, good spots are obtained.
