| Detection and Identification of Individual Nanoparticles Using Laser-Induced Breakdown Spectroscopy (LIBS)
|
|
As the use of nanoparticles in a wide range of applications continues to increase, the need for techniques to analyze these particles also grows. Javier Laserna of the University of Málaga, in Spain, has developed an approach to measure individual nanoparticles in air using optical trapping (OT) combined with laser-induced breakdown spectroscopy (LIBS). Laserna received the 2018 Lester W. Strock award for this development as well as his broader research on analytical methods and instrumentation using LIBS. He recently spoke to us about this work.

| SEC–ICP–OES Hyphenation: Speciation and Quantification of Polydimethylsiloxanes at Trace Levels
|
|
Polydimethylsiloxane (PDMS) compounds are ubiquitous; thus it is challenging to develop analytical methods that ensure their absence. A newly developed method combining size-exclusion chromatography with inductively coupled plasma–optical emission spectroscopy makes it possible to quantify ultratrace levels of PDMS in volatile and nonvolatile organic solvents. A complete range of molecular weights can also be distinguished with this approach.

15th International Conference on Laser Ablation
Location: Westin Maui Resort & Spa, Kaanapali, Maui-Hawaii, USA
Dates: September 8-13, 2019
The International Conference on Laser Ablation (COLA) is the premier conference in the field of laser ablation and applications. Since 1991, COLA has been bringing together laser scientists, end-users and industry to review state-of-the-art and next-generation laser ablation technologies. COLA is an interdisciplinary conference and the topics cover a wide range of scientific research that bridges the gap between basic science and applications / technology.  Learn more |

| Advancing Laser–Ablation ICP–MS |
|
Jorge Pisonero of the University of Oviedo studies the performance of the laser ablation process in laser ablation–inductively coupled plasma–mass spectrometry, examining aspects such as the morphology of the craters created during sampling and the role of laser fluence. He also studies the effect of these factors in specific applications of LA–ICP–MS. He recently spoke to us about this work.

| Portable Spatially Offset Raman Spectroscopy for Rapid Hazardous Materials Detection Within Sealed Containers |
|
Portable spatially offset Raman spectroscopy (SORS) enables rapid identification of materials concealed by a wide variety of nonmetallic sealed containers. This technique has been successfully used by the military, first responders, and customs and law enforcement operators in the detection of explosives, chemical agents, precursors and hazardous narcotics, thus enabling the acquisition of better information without disturbing the materials in question.
