    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

  • Microbes Make or Break Foods

    Monday, February 08, 2016
    Microbes in food make most people think of contamination, and with good reason: the list of dangerous microbes that can turn up in food is long. 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

  • A Micro Look at Microplates

    Monday, May 11, 2015
    Microplates, also known as microwell plates, are widely used in molecular biology, clinical and analytical workflows. Multiwell microplates are a staple for performing enzyme-linked immunosorbent assays (ELISAs). Read More

  • Cryoware: Essential Tools for Cryopreservation

    Friday, February 27, 2015
    Cryopreservation is the process of freezing cell cultures and storing them at extremely low temperatures. During that process, cultured cells are mixed with a cryo-protective solution and added to labeled storage vials, which are then cooled to ... 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

  • Atomic Absorption Spectrometry: The Science of Atomization

    Monday, August 25, 2014
    Atomic absorption spectrometers (AAS) measure the concentration of atoms in a sample in the parts-per-billion range based on their ability to absorb light at a specific wavelength. Most samples analyzed by AAS are liquid samples, and solid samples... Read More

  • ICP-MS Systems: Broadening the Scope of Trace Metal Testing

    Friday, July 25, 2014
    Inductively coupled plasma-mass spectrometry (ICP-MS) is a type of mass spectrometry for measuring most of the elements in the periodic table with detection limits at or below the parts-per-trillion range. Most samples analyzed by ICP-MS systems are ... 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

  • 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

  • GC Systems—Separating Compounds for Decades

    Friday, March 14, 2014
    Gas chromatography (GC), much like liquid chromatography (LC), is used to separate compounds by sending a mixture through a column with which the constituent compounds differentially interact, detecting them as they emerge. But while “LC compounds ... Read More

  • Take Your Samples Around the World in an Environmental Test Chamber

    Monday, February 17, 2014
    Did you ever wonder just how would your dependable lab equipment—or your smartphone, for that matter—function in, say, Antarctica? Or even just blocks from your home or lab? How long would your smartphone or tablet last if it were accidentally left ... 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
