  • Utilization of a TOC Analyzer for Low-Level Sample Analysis

    Thursday, February 03, 2011
    In a variety of industrial and environmental applications, the measurement of total organic carbon in water is an important analytical parameter in evaluating water quality. Read More

  • A Chromatography Detector for Multicomponent Analysis of Macromolecules and Polymers

    Thursday, February 03, 2011
    The properties of long-chain molecules and polymers are tailored to meet the demands of a specific application in a range of different ways. Read More

  • Dynamic Mechanical Analysis Under Controlled Conditions of Temperature and Relative Humidity

    Monday, January 24, 2011
    Historically, dynamic mechanical analysis (DMA) measurements have focused on the analysis of materials as a function of an imposed temperature profile. Read More

  • A Fully Automated Benchtop X-Ray Diffractometer for Structure Determination of Small Molecules

    Wednesday, January 12, 2011
    Single-crystal crystallography provides accurate and precise measurements of molecular dimensions in a way that no other science can begin to approach. Read More

  • A High-Performance, Fully Self-Contained, Rotational Viscometer

    Tuesday, December 21, 2010
    Routine viscosity measurements of materials are important in most industrial processes such as mixing and pumping, spraying and coating, extrusion, laydown, and leveling. Typically, a rotational rheometer is employed to measure the flow ... Read More

  • Rotational Viscometers and the Double Life of Structured Fluids

    Tuesday, November 30, 2010
    The products we stir, pump, spread, pour, and spray are usually thought of as liquids. Surprisingly, however, it can be demonstrated that they live a quiet double life as liquids when observed, but retreat into a little-known soft-solid character ... Read More

  • What is HAST Testing?

    Wednesday, September 29, 2010
    In effort to improve the reliability of products, many different industries, just to mention a few, including semiconductor, pharmaceutical, and solar companies turn to HAST testing as a shorter alternative to THB Testing. Read More

  • X-Ray Fluorescence (XRF) Analyzers

    Thursday, July 01, 2010
    In XRF, when an x-ray beam is directed at a sample, it dislodges electrons in the inner orbitals of the atoms that comprise it. Because that ionized state is so unstable, lower-energy electrons from outer electron shells (that is, farther from the ... 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

  • 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

  • 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

  • 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

  • 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
