The Reston Groundwater Dating Laboratory

GW Dating Lab Equipment Overview:

Shimadzu GC-8A with an ECD for the analysis of ultra-trace concentrations of SF6 in water and air. photo

Shimadzu GC-8A Gas Chromatograph (GC) with an Electron Capture Detector (ECD), for the analysis of CFCs and other halocarbons. photo

Hewlett Packard GC, with a Thermal Conductivity Detector (TCD) and a Flame Ionization Detector (FID), for the analysis of the atmospheric gases N2, O2, Ar, CO2, and CH4. photo

Shimadzu GC Mini-2 used in the past for CFC analysis, currently used for SF5CF3 and CFC-13. photo

Shimadzu GC-14A GC with two ECDs and capillary columns capable of determining a wide range of halocarbons in water and gases including CFCs, Methyl Chloroform, and CCl4. This GC has also been used to analyze gas and water samples for SF6.

Shimadzu GC-14A GC with a TCD, Photo-Ionization Detector (PID), and FID, for the analysis of He, Ne, H2, Ar or O2, N2, and CH4 in ground water, and in air, including unsaturated-zone air. This GC can also be used for the analysis of a wide range of organic and inorganic gases. photo

Shimadzu GC8A with ECD used for low level VOC analysis. photo

Hewlett Packard GC-Mass Spectrometer (GC-MS) with Mass Selective Detector 5973, for the analysis of organic compounds dissolved in ground water. photo

Agilent model 6890A GC with an ECD used for new tracer methods research and development.

Agilent G2350A Atomic Emission Detector used for new tracer methods research and development.
