  • HPLC: A Versatile, Powerful Separations and Analysis Technique

    Friday, June 05, 2015
    High-performance liquid chromatography, also known as high-pressure liquid chromatography (both referred to as HPLC) is a highly versatile, sensitive technique for conducting separations and analyses. read more

  • GC/MS Technology: Improving Sensitivity and Results

    Monday, May 11, 2015
    Gas chromatography/mass spectrometry (GC/MS) is a highly selective analytical technique for identifying compounds using mass detection. As in liquid chromatography (LC), gas chromatography relies on a mobile phase, but in GC, the mobile phase is a gas, not a liquid solvent. 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

  • Shaking Cells to Produce Novel Products

    Friday, April 10, 2015
    “Biotechnology” is a term that has only been used for a few decades. However, the fundamentals of biotechnology, including the concepts of shaking, heating or cooling a fermenting mixture, actually have been used for thousands of years. read more

  • Beyond Light: Characterizing the Molecular World With Scanning Electron Microscopes

    Friday, April 10, 2015
    Centuries ago, glass lenses were employed to visually enhance small objects beyond the physical abilityBof the human eye. Light and compound mi- croscopes led to the birth of microbiology. However, the physical properties of visible light greatly limited the resolving power of optical microscopes. 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 frequency of changing analytical requirements may ... read more
