Liquid Chromatography/Mass Spectrometry (LC/MS/MS)

A benchtop triple stage quadrupole mass spectrometry system (LC/MS/MS) is used for research and development of new methods. This instrument includes the following:

    • Z-Spray atmospheric pressure ionization LC/MS interface
    • Precision engineered analizer of mass range 2-2000 amu
    • Positive and negative ionization capability
    • Coaxial probe for low flow rate electospray operation
    • MassLynx instrument control and data acquisition interface

A new highly sensitive high performance bench top triple quadrupole Atmostpheric Pressure Ionization (API) Liquid Chromatography/Mass Spectrometry system (LC/MS/MS) was added to the laboratory in 2006. This instrument includes the following:

    • TURBO V (TM) ion source which contributes to low sensitivity and eliminates cross-contamination
    • PhotoSpray(TM) ion source which expands the range of compounds that can be analyzed
    • LINAC (TM) collision call which ensures for the maximum ion transfer in MS/MS mode
    • Analyst (TM) software which includes the InteliiQuan integration system
LC/MS/MS analyses performed by the Organic Geochemistry Research Laboratory are as follows:
  • Antibotics and Degradation Products (LCAB)
  • Glyphosate, AMPA, and Glufosinate Online (LCGY)
  • Antibiotic soils and sediments (LCAS) - Custom request basis only
  • Glyphosate soils and sediments (LCGS) - Custom request basis only
