This article will be focusing on a very commonly used instrumentation, Liquid Chromatography-mass spectrometry (LC-MS). Who wins in the battle between LC-QqQ, QTOF, TOF?
What comes to mind when you think of fluorine? The sodium fluoride in toothpaste and mouthwash is the typical, everyday example that most people think of, but fluorine plays a large role in many other compounds. Pure fluorine is a highly reactive and poisonous gas, while fluorinated compounds are incredibly stable, fairly nontoxic, and used in many real-life applications.

How do we know we are safe with what we eat? Here, the authors introduce a fast and easy way to dig out the pesticides from our food for analysis.
Finding ways to create order is a common theme in science. Here researchers are trying to carefully arrange chromophores in order to create better solar cells (among other potential uses). In particular, these chemists are trying to make porphyrins stand up on a surface creating stacks of porphyrins that are a well defined distance from each other and from the surface they are attached to.
Here the authors describe all of the consumer products that are utterly and completely chemical-free. I hate to ruin the surprise, but their aren’t any.
This study further supports a connection between acid deposition and forest decline. The authors state, “Continued vigilance in the control of acid rain precursors will be needed to correct these problems, and aggressive options to reduce pollution in rapidly industrializing regions of Latin America, Asia, and Africa are warranted.”
