Syracuse, New York and Zurich, Switzerland - October 14, 2002 - INFICON Holding AG (SWX Swiss Exchange and NASDAQ: IFCN), a leading manufacturer of vacuum instrumentation and critical sensor technologies for the semiconductor and related industries and other industrial applications, has received a $1.2 million order for the HAPSITE Field Portable Gas Chromatograph/Mass Spectrometer from the U.S. Department of Defense. Most of the HAPSITE instruments will ship in the fourth quarter to the U.S. Air Force.

The HAPSITE Field Portable GC/MS is another example of INFICON expertise in gas sensing and vacuum technology. It is used for fast, on-site detection and analysis of chemical agents and toxic materials.
