Instruments

  • Inductively Coupled Plasma Mass/Optical Emission Spectroscopy (ICP-MS/OES)

    Measures total elemental composition in water. ICP-MS is used specifically for measuring trace concentrations as low as ng/L, and ICP-OES is used to measure concentrations higher than 0.1 mg/L.

    ChEE/KORES

  • Zeta Potential Analyzer

    Zeta potential is a measure of the electrical charge at the interface of a particle and its surrounding liquid.

    KORES

  • Biosafety Tools

    Vital equipment for the protection of researchers and the environment from biohazards. This includes biosafety cabinets (BSCs) and personal protective equipment (PPE).

    NIHI

  • Polymerase Chain Reaction (PCR)

    Lab technique used to create copies of a specific DNA sequence.

    NIHI

  • DNA Extraction

    Process where DNA may be isolated from biological material.

    NIHI

  • High-Performance Liquid Chromatography (HPLC)

    A separation technique used to identify and quantify compounds in a sample.

    ChEE

  • X-ray Photoelectron Spectroscopy (XPS)

    Determines oxidation states and atomic composition in the “near surface” region of solid samples.

    LESSA

  • Fourier Transform Infrared Spectroscopy (FTIR)

    Tool used to identify and analyze the chemical composition of materials by how the material interacts with infrared light.

    EPSILON

  • Scanning Electron Microscope (SEM)

    An imaging tool for determining morphological characteristics at the micron scale.

    EPSILON

  • Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)

    System which combines the separation capabilities of liquid chromatography and the mass identification of mass spectrometry.

    ALEC

  • Ion Chromatography (IC)

    Measures anion and cation concentrations in water.
