LCGC Blog: Rethinking Undergraduate Chemistry Education

I am rolling through the 12th year of my independent career here at U.T. Arlington. In that time, my group has worked on a lot of different and exciting research topics. As I reflect, I am quite certain that my vision 12 years ago would incorporate virtually nothing of what I am actually doing now. It is for this reason that I state continuously that I love my job and that I love how in analytical chemistry, you are always on the learning curve. read more

Webinar: Fast, Reproducible Cannabis Potency and Pesticide Analysis

One of the newest and exciting fields in analytical testing is medical/retail marijuana. The need for economical, fast, reproducible testing protocols exists. Product purity, potency and pesticide analysis are areas of major concern for both quality control and patient consumer safety. The consistent extraction of cannabinoids and pesticides for analytical quantitation is critical. PLE can dramatically improve reproducibility of results, speed and cost of Cannabis extractions.

Asymmetric Flow Field-Flow Fractionation Analysis of Engineered Nanoparticles in Mouthwashes and Their Interaction with Saliva

The evaluation of the oral uptake of engineered nanoparticles (ENPs) contained in personal care products like mouthwashes is of great relevance to estimate the potential hazards and the toxicity of engineered nanomaterials (ENMs). Within this study, two experimental scenarios with commercially available mouthwashes (M1 and M2) are investigated in relation to the product characterization and the human oral exposure with a special focus on the time-dependent interaction with saliva via state-of-the-art AF4 coupled to multiple detector systems. read more
