Learn about our AROMA analyzers


AROMA-VOC is a high-performance chemical analyzer that provides real-time data on chemicals in air, water, and soil. The instrument provides analysis for key compounds of high risk including BTEX, 1,3-butadiene, chlorinated solvents including trichloroethylene (TCE), and styrene ⁠— making it an ideal for volatile organic compound (VOC) monitoring. 

Results are quick — less than 5 seconds in RapidScan mode and 10 minutes in full analysis mode — and have method detection limits as low as 1 pptv. In RapidScan mode, our proprietary algorithms provide large molecule concentrations by classification and speciated small molecule concentrations, including for methane.

The instrument operates as a comprehensive mobile analysis platform with built-in GPS, pressure-logging, and integration options for logging of auxiliary RS-232 or RS-485 sensors such as anemometers. Designed for remote and mobile applications, AROMA-VOC can be programmed to perform automatic analyses while simultaneously reporting data to anywhere in the world.
