Chemical Heritage Foundation instrumentation manual collection: Advertising materials

These materials may be reprints of scholarly articles, or reports, or data sheets. The advertising material also varies in intent. Material designated as technical advertising is more theoretical in nature and directed toward end-users of the product. Trade advertising is more general in nature. Colorful and filled with superlatives, it was clearly aimed at administrators and purchasing personnel. The ads are filed by company name in a filing cabinet system. Some of this material is accompanied by correspondence which usually relates to issues of pricing or product improvement. Some of the files originally contained photographs of the equipment. These photographs were provided by the manufacturers for publicity purposes. They have been removed during processing and will now be found in the image archives.
