Extraction and determination of sulfonamides, macrolides, and trimethoprim in sewage sludge.
Göbel Aa, Thomsen A, McArdell CS, Alder AC, Giger W, Theiss N, Löffler D, Ternes TA. Göbel Aa, et al. J Chromatogr A. 2005 Sep 2;1085(2):179-89. doi: 10.1016/j.chroma.2005.05.051. J Chromatogr A. 2005. PMID: 16106697
A mixture of water/methanol (50:50, v/v) was found as the most efficient extraction solvent. A temperature of 100 degrees C and a pressure of 100 bar were chosen for extraction. Two cycles of 5 min each efficiently extracted at least 97% of the total extractable amount of …

Utilization of large volume zwitterionic hydrophilic interaction liquid chromatography for the analysis of polar pharmaceuticals in aqueous environmental samples: Benefits and limitations.
Boulard L, Dierkes G, Ternes T. Boulard L, et al. J Chromatogr A. 2018 Feb 2;1535:27-43. doi: 10.1016/j.chroma.2017.12.023. Epub 2017 Dec 11. J Chromatogr A. 2018. PMID: 29325802
These matrix effects and those of other analytes could be efficiently compensated by using deuterated, (13)C and (15)N-labeled internal standards. The developed method was able to detect the selected 27 analytes in treated wastewater, surface water and groundwater down to …

The determination of the linear alkylbenzene sulfonate isomers in water samples by gas-chromatography/mass spectrometry.
Moldovan Z, Avram V, Marincas O, Petrov P, Ternes T. Moldovan Z, et al. J Chromatogr A. 2011 Jan 14;1218(2):343-9. doi: 10.1016/j.chroma.2010.11.043. Epub 2010 Nov 27. J Chromatogr A. 2011. PMID: 21159344
This paper presents the mass spectra of 20 compounds, the proposed mechanism of formation of the diagnostic ions obtained by EI-MS and the distribution of individual isomers in water samples collected from compartments of WWTP. The individual isomers from four homolog series C …
