- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- Diamonds Are Forever
Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
Chemical bonding resulting from the transfer of one or more electrons from one atom or a group of atoms to another.
The substance that oxidizes another substance and is reduced.
Covalent bond in which there is an unsymmetrical distribution of electron density.
A method used to determine the molecular weights of volatile liquids.
Equation for a chemical reaction in which all formulas are written as if all substances existed as molecules, only complete formulas are used.
Very weak and very short-range attractive forces between short-lived temporary (induced) dipoles, also called dispersion Forces.
A salt or ester of xanthic acid. Many xanthates have a yellow color. Xanthates are used as flotation agents in mineral processing.

The interaction of orbitals on different atoms in the same region of space.
The arrangement of atoms (not lone pairs of electrons) around a central atom of a molecule or polyatomic ion.
An algebraic increase in the oxidation number, may correspond to a loss of electrons.
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.
The reaction of a substance with water or its ions.
The point at which chemically equivalent amounts of reactants have reacted.
Photochemically produced oxidizing agents capable of causing damage to plants and animals.
