AIRCO/BOC PROVIDES SOLUTION TO LOW-LEVEL TRANSIENT IMPURITIES

 AIRCO/BOC PROVIDES SOLUTION TO LOW-LEVEL TRANSIENT IMPURITIES
 MURRAY HILL, N.J., Nov. 10 /PRNewswire/ -- Airco/BOC has introduced a new service to help semiconductor manufacturers identify and eliminate trace impurities in bulk nitrogen, argon, hydrogen and helium gas systems.
 Proprietary calibration and sampling technologies developed by The BOC Group Technical Center in Murray Hill, N.J. significantly improve both the detection limits and response time of a new BOC portable atmospheric pressure ionization mass spectrometer (Hitachi UG-302-P APIMS). The BOC APIMS is capable of measuring part-per-trillion (ppt) levels of impurities such as moisture, oxygen, carbon monoxide, carbon dioxide and methane. More importantly, the rapid response time of the instrument allows the detection of damaging transient phenomena such as oxygen spiking.
 The new portable APIMS is now being sent to Airco/BOC customer sites where, within only a few days of arrival, it is capable of analysis measurement that can identify the source of any gas system purity fluctuations. Once the system is characterized, Airco then recommends solutions to customers based on The BOC Group's extensive component and gas system experience. Validation of problem resolution also can be provided by the APIMS.
 The Analytical Services Group of the BOC Group Technical Center commissioned and operates the instrument as part of the global BOC SPECTRA 100(TM) program.
 Airco Gases is a leading manufacturer of industrial gases and gas handling technology in the United States. Airco is a member of the BOC Group, the worldwide gases, health care, vacuum technology and distribution services company which operates in some 60 countries and last year had sales of $5.2 billion.
