Description
[Image Permanence Institute, Rochester, NY] A trademark for indicator strips designed to detect volatile acidic components released by the decomposition of Cellulose acetate. A-D, or Acid Detector, strips contain a PH sensitive dye (Bromcresol green) that changes from blue to green to yellow in the presence of any acidic vapors. The color reading, taken within 24 hours of exposure, is compared to a chart provided with the strips. The strips were developed by Fischer and Reilly (1995), who were honored with an Academy Award in 1997 for their contribution to the preservation of the history of motion pictures.
Synonyms and Related Terms
Acid Detector strips; AD-Streifen (Deut.); indicator strip
Other Properties
RH should be about 50% for optimum results.
Hazards and Safety
Exposure to light will fade the colorant.
