Organic Geochemistry Research Laboratory
Liquid Chromatography/Mass Spectrometry (LC/MS)
Two Agilent 1100 Series liquid chromatography/mass spectrometers equipped with a
diode array detector are in use for laboratory projects, methods development,
and other special analyses.
LC/MS Analysis
LC/MS analyses performed by the Organic Geochemistry Research Laboratory are as follows.
The laboratory code is indicated in parentheses after the method description.
- Acetamide Parents and Degradation Products (LCPD)
- Triazine and Phenylurea Parents and Degradation products (LCEA)
- Isoxaflutole and Degradation Products (LCIX) - Custom request basis only

The USGS has collected hydrologic information in Kansas since 1895 with the first USGS Cooperative
Water Program funding agreement for 6 streamflow gages with the Kansas Water Board. USGS collects streamflow
and gage-height data; reservoir content; water-quality and water-quantity data; suspended-sediment data;
and groundwater levels. Hydrologic studies are conducted on national, regional, statewide, and local levels.
The USGS in Kansas works cooperatively with 31 Federal, State, and local agencies, such as the Kansas Water Office, the U.S.Army Corps of Engineers, and the City of Wichita
