Pyrolysis DART: industrial materials, polymers

Although high-molecular-weight materials such as industrial polymers cannot be detected intact by DART, increasing the DART heater to 350°C or higher can result in degradation to produce characteristic “fingerprint” fragments.

Thermal desorption/pyrolysis DART: even better for materials and polymers

A thermal desorption/pyrolysis stage (The Biochromato, Inc. “IonRocket”) is designed for use with DART. Highly reproducible thermal desorption profiles show outgassing, additives, and high-quality pyrolysis DART mass spectra for materials. Thermal desorption/pyrolysis analysis of duct tapes and fibers is discussed in separate application notes:
