Description
The brochure discusses the use of the IR-2 spectrophotometer in an air pollution study. Though undated, the referenced instrument models and logo narrow the date of the brochure's publication to somewhere between the late 1940s to 1956, with 1955 suggested by comparison to the content of subsequent brochures in the series.
