  • Temperature Chambers and Environmental Test Chambers

    Monday, April 20, 2009
    The best way to understand how a product or material will perform in the field or over time is to use a laboratory test chamber to model those conditions. This is done in one of two ways: the test chamber may model the conditions exactly as they are,... Read More

  • Gas Chromatography (GC)

    Wednesday, May 13, 2009
    In the biological sciences, to go-to method for molecular separation is liquid chromatography (LC). But those engaged in forensics, petrochemical research, food and flavor development, environmental science, and metabolomics take another approach: ... Read More

  • Spectrophotometers

    Friday, June 05, 2009
    Turn on your kitchen sink. Is the water fit to drink? One way to make that determination is with your eyes. Is it turbid? Colored? The optical properties of the water can help you decide. Researchers in fields from biology and chemistry to materials... Read More

  • Particle Size Analysis

    Thursday, July 02, 2009
    Have you ever dug into an old pint of ice cream from the back of the freezer, only to find that your mint chocolate chip has morphed from smooth and creamy to icy and granular? Both are ice and cream, yet nobody would call the latter preferable. It's... Read More

  • Mass Spectrometry Ionization Sources

    Saturday, August 15, 2009
    Whatever their configuration, mass spectrometers comprise two basic components: an ionization source and a mass analyzer. The former, as its name implies, ionizes molecules; the latter measures their mass—or more accurately, their mass-to-charge (m/z... Read More

  • Mass Spectrometry Mass Analyzers

    Tuesday, September 22, 2009
    Whatever their configuration, mass spectrometers comprise three basic components: an ionization source, a mass analyzer, and a detector. The ionization source, as its name implies, produces the charged molecules that can be seen by the detector; the ... Read More

  • GC and Environmental Testing

    Thursday, November 12, 2009
    Though the term may evoke tree-huggers and spotted owl enthusiasts, environmental science is actually a surprisingly broad chemistry sub-discipline. It involves testing a diverse array of matrices—earth, air, and water—for highly divergent classes of... Read More

  • HPLC Detectors

    Wednesday, December 23, 2009
    In the world of chromatography, separation is only half the battle. The other half: detecting what's coming off the column. After all, what good is separation if you cannot tell it occurred? To paraphrase the classic riddle, if a compound emerges ... Read More

  • Raman Spectroscopy

    Monday, April 19, 2010
    Raman spectroscopy uses laser energy to molecularly "fingerprint" materials nondestructively and without contact. As a result, the technique is finding use in fields as diverse as homeland security, biomedicine, pharmaceutical manufacturing, and ... Read More

  • Piezo Motors and Actuators: Streamlining Medical Device Performance

    Tuesday, June 15, 2010
    A significant improvement over conventional electromagnetic motors for the execution of precise movements with medical equipment, the latest piezoceramic motors and actuators are more compact, require lower voltage, deliver higher torque, have ... Read More
