Do you know that nanomaterials (down to 10,000 smaller than the diameter of a human hair) can be natural (viruses, wax crystals on a lotus leaf, spider silk, butterfly wing scales, blood, milk) or manufactured? (link and source Wikipedia.) Manufactured nanoparticles are increasingly being used in pharma drug delivery, disease detection, energy production, and even food and have triggered growing concern regarding their environmental behavior in aquatic environments. The ability to detect and quantify nanomaterials in complex water matrices has become an important issue (link to EU nanomaterials webpage).
Here, I am pleased to present an on-demand webinar and a poster note on the use of sample preparation and LC-MS techniques and one of our chromatography columns for the analysis of nanomaterials and emerging contaminants, such as pharma drugs, in the environment.
This webinar featuresDamiá Barceló, Ph.D., Research Professor, Institute of Environmental Assessment and Water Research (Barcelona, Spain) and Director, Catalan Institute for Water Research (Girona, Spain) in conversation with Laura Bush, Editorial Director, LCGC and Spectroscopy. (To play the webinar, click the title above to access a short registration form.)
The topics discussed include the analysis and identification of emerging contaminants and their transformation products in river water, urban water, and hospital wastewaters. Results of several different sample preparation methods (such as on-line solid-phase extraction and turbulent flow cleanup) followed by liquid chromatography with triple quadrupole-mass spectrometry and orbital ion trap mass spectrometry analysis are presented.

The following contaminant examples are presented:
- Endocrine disruptors and related compounds in river and wastewaters
- Transformation products of the anticonvulsant drug lamotrigine
- Tetracycline after enzymatic degradation of wastewaters
- Nanomaterial fullerenes in suspended materials in wastewater and river water
In this poster note, one of our phenyl HPLC columns (Thermo Scientific Acclaim Phenyl-1 Column) is used for the analysis of aromatic hydrocarbons, steroids, fat-soluble vitamins, and phospholipids including buckministerfullerene (C60), a nanoparticle composed of carbon. This particular fullerene is of special interest because of the widespread application of nanocarbon technology. In the experiment, fullerenes in fullerene soot were separated under isocratic conditions with heptane/isopropanol mobile phase using both a C18 column and the phenyl column. Compared to the C18 column, the phenyl column exhibits different selectivity and provides better resolution for minor components.
