Designed for use at passenger security checkpoints for screening of carry-on baggage, the IONSCAN 500DT from Smiths Detection of Pine Brook, New Jersey, is an advanced explosives detector that can detect trace amounts of explosive substances from a single sample in a matter of seconds. The desktop model also detects and identifies narcotics in the same analysis. An advanced sampling wand eliminates the need for the operator to handle the sample swab after every sample. The operator navigates through the software using a large color touch-screen display. The unit is now officially certified by the U.S. Transportation Security Administration through its Certification Plan for Explosive Trace Detection Equipment.
