General view of Ernest Bartha, director of the Elyria City Health Department Laboratory, injecting a drug evidence sample into a Perkin-Elmer gas chromatograph. Per notations accompanying the photograph, the instrument is used to analyze and identify the constituents present in complex mixtures of drugs, narcotics, and arson evidence gathered by the Elyria (Ohio) Police Department for forensic analysis. Several such samples are visible in the foreground, while the results of these analyses are graphed on charts such as the one visible on the right. In addition to forensic analysis, the laboratory also conducts health analyses of food, water, and human sputum samples, as well as pollution analyses of waste waters and pesticide residues.
