The laboratory identified a barbiturate in the sample through chromatography and mass spectrometry.

In mid-20th-century psychiatric literature, barbiturism was described as a chronic, debilitating condition caused by excessive use of barbiturates.

In the undergraduate lab, she synthesized barbituric acid and analyzed its melting point to compare it with literature values.
