An Update on Assessing Heavy Metals in Pet Food with ICP-MS
December 01, 2020
A 2009 study found many heavy metals in pet food. Has anything changed?
Where Spectroscopy Is Heading
July 01, 2020
We are pleased to present here part II of our celebration of Spectroscopy’s 35th year of publishing. For this special coverage, we asked leading spectroscopists to share their perspectives on a range of spectroscopic techniques and applications.
Celebrating 35 Years of Spectroscopy
June 01, 2020
In celebration of Spectroscopy’s 35th Anniversary, leading spectroscopists discuss important issues and challenges in analytical spectroscopy.
Detection and Identification of Individual Nanoparticles Using Laser-Induced Breakdown Spectroscopy (LIBS)
February 08, 2019
As the use of nanoparticles in a wide range of applications continues to increase, the need for techniques to analyze these particles also increases. 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.
Not All Nanoparticle Analysis Challenges are Created Equal
September 10, 2018
The detection, quantitation, and characterization of nanoparticles using inductively coupled plasma–mass spectrometry (ICP-MS), and in particular using single-particle ICP-MS (SP-ICP-MS), has developed significantly in recent years. However, the difficulties involved in this type of analysis vary, depending on the composition of the nanoparticles. Martín Resano of the University of Zaragoza, together with colleagues from Ghent University, has recently developed a method for characterizing nanoparticles made from silicon dioxide (Si02), which are much more challenging to detect than those made from silver or gold. He recently spoke to us about this work.
