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)
- Chlorothalonil and Degradation Products (LCCD)
- Isoxaflutole and Degradation Products (LCIX)
