The Dynatherm product line of sample collection and introduction instruments for gas chromatography serves the laboratory test and measurement markets. Dynatherm instruments provide laboratory personnel from both government and commercial activities with the means to collect trace organic chemicals from air, water and soil samples, as well as diverse food products such as coffee, grains, juices, chocolate, flavorings and their packaging materials. A variety of government and industrial clients ranging from the U.S. Army and the Environmental Protection Agency, to Kellogg Co., Hershey Foods and General Foods Corp. currently use Dynatherm instrumentation and methodologies.

In much the same way as a vacuum cleaner filters dust from the air as it sweeps over a surface, Dynatherm instruments capture the chemicals to be analyzed on adsorbent material packed in glass cartridges, and then introduce the collected chemicals into various analytical instruments for component identification and quantitative measurement. The technology provides customers with solutions to problems encountered during sampling, such as concentrating low-level organic components, typically at 1 part analyte per million or billion parts of total collected sample.

The current line of Dynatherm instruments provides both manual and automated approaches to thermal desorption. The ACEM 900 is a single-tube desorber that desorbs one tube at a time. The MTDU 910 and 916 are multi-tube devices that automate the analysis process of samples that have been collected onto adsorbent cartridges at remote locations. The IACEM 980 is a continuous sampler that serves the industrial hygiene market for analysis of worker exposure to hazardous workplace chemicals, as well as providing monitoring capability required by the federal Clean Air Act Amendment of 1990.

In the early 1990s, several laboratory equipment manufacturers headed by E-N-G Mobile Systems teamed to produce the Real Time Analytical Platform (RTAP), a mobile laboratory that provides airborne exposure level assessments of dangerous chemicals for the U.S. Army.

Terrorist activities and events in Iraq created a need for other types of mobile instrumentation to detect airborne chemical weapons, pre-cursor compounds, and manufacturing by-products. Dynatherm instruments are used in the Flyaway Modular Laboratory, which is designed to be easily moved in containerized modules and transportable on standard commercial aircraft and be operational within 4-6 hours anywhere in the world. The package is totally self-contained and includes power and gas generators.

Dynatherm air monitors were used in the development of the TO-15 and TO-17 ambient air methods issued by the U.S. Environmental Protection Agency. These methods allow government agencies, environmental contract laboratories, and industrial customers to use materials and methods that characterize the core technology of Dynatherm instruments for assessment of air toxics and other volatile organic compounds (VOCs).

Dynatherm instruments have contributed significantly to problem solving method development projects at the U. S. Department of Defense, EPA, NIOSH and OSHA. Addressing the need for robust, reliable air sampling and concentration techniques, the various instruments are used extensively in applications to:

  • evaluate long- and short-term chemical exposures in the workplace,
  • detect/identify/quantify chemicals generated during terrorist and criminal activities,
  • assess VOCs and toxic industrial compounds (TICs) for ambient and indoor air quality, and
  • monitor challenge atmospheres in environmental chamber studies.
