Detecting Organics Using Fluorescence Spectroscopy



Nathan Bramall, NASA Ames Space Science Division

Many important organic molecules fluoresce strongly enough to allow for their detection in terrestrial soils at the ppm level or better. Dr. Bramall will discuss a method has advantages over other methods of detecting organics in that it requires no reagents, is very quick, requires no sample handling, and can be rather specific. He has have developed several instruments and instrument concepts that will be presented.
