In 1982 IBM established a series of independent business units (IBUs) to develop and pursue opportunities in specialized marketplaces, such as robotics and biomedical technology. One of those IBUs -- IBM Instruments, Inc., headquartered in Danbury, Conn. -- introduced in the mid-80s the EC/250 as a cost effective tool to determine low levels of hydrogen peroxide residuals in aseptic packaging of foods.
The EC/250 responded to a U.S. Food & Drug Administration requirement that food manufacturers maintain levels of hydrogen peroxide in sterilized food packages at levels lower than 0.1 ppm after 48 hours. IBM's device gave the manufacturers the ability to track hydrogen peroxide levels with minimum operator effort through push button operation and direct display of peroxide concentration on its digital readout.
The EC/250 incorporated a highly reliable internal calibrator, and could be easily adapted for laboratory use, industrial environments and field operations.
IBM Instruments ceased operations in 1987.
