spectroscopic (GC/MS) procedures to give confusing results when compounds
are not adequately separated by the chromatographic system. These compounds
may also mask analytes of interest by reacting or simply associating
with them.

Organic chemistry deals with the relatively simple organic compounds, most
of which are easily synthesized in the chemical laboratory and are found in all
environments. They are composed of carbon, hydrogen, oxygen, and nitrogen
