In addition to a full complement of traditional analytical capabilities, Excet is the provider of Direct Analysis in Real Time (DART) expertise to ECBC. DART is a revolutionary ion source able to ionize compounds from surfaces, without direct contact, in open air in a matter of a few seconds. It permits highly sensitive mass spectral detection and identification of most compounds with little or no sample preparation required. It is particularly sensitive to chemical weapons and explosives. Our employees are responsible not only for optimizing and proving this promising new technology, but advancing it as well, generating several enhancements which are actively in the process of patent submission. Their work has produced numerous peer-reviewed journal articles, oral presentations and a book chapter in Forensic Analysis on the Cutting Edge: New Methods for Trace Evidence Analysis.
