Insights Toward Standardization of the Analysis of Microplastics by Infrared Microscopy

August 01, 2020

Here we conduct an evaluation of significant operational parameters of IR microscopy for accurately determining the size of microplastics, with the overarching goal of outlining performance parameters that will help in the standardization of microplastics analysis.

A MATLAB Application for Calculation of Cell Pathlength in Absorption Transmission Infrared Spectroscopy

August 01, 2020

Reliable quantitative FT-IR measurements require that the pathlength be known to within 1%. Pathlength estimations based on nominal spacer thickness are not reliable and require that the actual pathlength be measured for accurate data. We demonstrate how.

August 01, 2020

SERS offers many advantages. However, there are several issues to be aware of when trying to use SERS signals in analytical applications.

Optical Measurement of the Reflectance Behavior of Z93, the Thermal Coating on the International Space Station

August 01, 2020

Measurements of the optical proper ties of a ceramic material, Z93, which is in current use on the International Space Station (ISS), reveal why this material is successful for thermal control in the ISS implementation, and also point to potential future material design improvements.

Characterization of GeSbSe Thin Films Synthesized by the Conventional Melt-Quenching Method

August 01, 2020

Spectroscopic ellipsometry, correlated with UV-vis-NIR spectroscopy, is used to determine the optical constants of thin films, such as in GexSb40-xSe60 chalcogenide glass.

A Survey of Chemometric Methods Used in Spectroscopy

Advancing Trace Elemental and Speciation Analysis with a Focus on Metrology

July 10, 2020

For more than 20 years, Heidi Goenaga-Infante, a science fellow and the leader of the inorganic analysis team at LGC, has been working on elemental and speciation analysis. Two recent areas of investigation include the analysis of trace metals in biological samples, and the study of nanomaterials. In these studies, Goenaga-Infante puts particular emphasis on metrology-advancing this work by developing validated reference methodologies. Goenaga-Infante is the 2020 recipient of the Lester W. Strock Award from Society of Applied Spectroscopy (SAS) and the SAS New England Regional Section, in recognition of her contributions to the field of analytical atomic spectrometry, and she recently spoke to us about her work. This interview is part of an ongoing series of interviews with the winners of awards that are presented at the SciX conference.

Spectroscopy and LCGC North America are proud to announce that Lydia Neguse of The California Academy of Mathematics and Science School in Carson, California, has been named the winner of the 2020 Most Outstanding Female in Chemistry or Chemical Analysis award at the Los Angeles County Science & Engineering Fair.

Assessing Heavy Metals in Pet Food with ICP-MS: An Update

July 08, 2020

In 2009, a group of researchers conducted a study, using inductively coupled plasma–mass spectrometry (ICP-MS), to determine if heavy metal contaminants were present in a variety of pet foods . Results were compared to 2009 EPA Reference Dose (RfD) and World Health Organization (WHO) Tolerable Daily Intake (TDI) levels, scaled to the sizes of pets. In the intervening decade, the U.S. Food Safety Modernization Act (FMSA) was enacted, and pet food became one of the targets of scrutiny. The team conducted a follow-up study in 2019, revisiting the pet food brands first analyzed in 2009 as well as new brands that have emerged since, to see if anything changed significantly in the intervening decade. The new study used updated cryogenic and microwave technologies for sample preparation before ICP-MS analysis. We spoke to the study’s lead author, Patricia Atkins, a Senior Application Scientist at Spex CertiPrep, about this investigation.
