The mass spectrometer is one of the most versatile instruments available to the analytical chemist. It can analyze samples that are gases, liquids, or solids. It is used to analyze individual atoms or complex biopolymers. When coupled with chromatography, which is a broad range of...
What happens chemically when fruit turns brown
By: Brian Dodson
We have all been there. Preparing a special salad, or an apple pie, wanting everything to be perfect for our family and guests. Then, before the blink of an eye, the pristine juicy cut surfaces of the fruit begin to turn brown and ugly. We...

The Noble Gas neon is one of the most inert elements known. Finding interesting facts about an element that does not do very much is difficult but I’ll try. Starting with the elements basic properties, its atomic weight is 20.1797 and its density...
Crystal growing made simple
By: A. C. Bowie
Growing crystals is easy, fun, and, a lot of times, edible and pretty to look at. It’s also a simple way to introduce younger kids to some basic elements of chemistry. It allows the opportunity to practice skills like careful measuring and the use...
Crystal growing made simple
