  • Spectrophotometers Overview

    Tuesday, April 23, 2013
    Spectrophotometers measure the amount of light of a specific wavelength that is absorbed by a sample. A spectrophotometer is used chiefly to measure the concentration of analytes in solutions, but is also used to characterize liquid and solid ... Read More

  • Portable XRF: Nondestructive Testing in Seconds

    Monday, July 01, 2013
    We are all familiar with X-rays, the short, highly energetic waves used by dentists to check for cavities, and by airport screeners to look for contraband. We experience fluorescence—the phenomenon by which something absorbs energy and in turn ... Read More

  • UHPLC: Pushing the Limits of HPLC

    Friday, August 09, 2013
    For fields that rely on liquid chromatography, the standard today is usually ultra high-performance liquid chromatography (UHPLC). And with good reason—compared to its chromatography predecessors, UHPLC is faster, provides better separation, and... Read More

  • Particle Sizing Systems: Key to QC and Product Testing

    Thursday, September 05, 2013
    A particle size analyzer, also known as a particle sizer, is used to measure the sizes of particles in a sample. It can also determine distributions of particle sizes. Read More

  • Differential Scanning Calorimetry—A Fundamental Thermal Analysis Tool

    Thursday, October 24, 2013
    A differential scanning calorimeter (DSC) is a benchtop instrument used to determine thermodynamic transitions and heat capacities of a variety of substances. A small sample—typically 5–20 mg, around the size of the tip of a #2 pencil—is placed in ... Read More

  • Environmental Monitoring, Protein Determination, and Quality Control: An Introduction to Nitrogen Analyzers

    Thursday, April 24, 2014
    Nitrogen is a common element, present in every living organism. It is vital to lifecycles and important in many industrial processes in its different forms. Organic nitrogen occurs in proteins, peptides, nucleic acids, urea, and many synthetic ... Read More

  • Lab Technology Face Off: ICP-AES vs. ICP-OES vs. ICP-MS

    Thursday, July 17, 2014
    The specificity of elemental analysis required and the laboratory budget are the biggest considerations in choosing an ICP-OES system over an ICP-MS system. The amount of samples to be tested per day, as well as regulatory testing standards and ... Read More

  • Detecting and Managing Water Contaminants in the Laboratory

    Thursday, October 16, 2014
    Water purity is a fundamentally important factor in many laboratories, yet it is frequently overlooked. Researchers use water in most lab processes, and poor water quality can quickly lead to mounting problems, resulting in the generation of ... Read More

  • Environmental Mass Spectrometry

    Monday, February 08, 2016
    Humans and nature can pollute the environment, and our health often depends on tracking and analyzing the toxic compounds. Read More

  • Pharmaceutical Mass Spectrometry

    Wednesday, March 09, 2016
    In the pharmaceutical industry, accurately identifying the components of a mixture can be the difference between life and death. Read More
