Monitoring Emissions in Real Time

Dr. Somenath Mitra has invented a device to monitor NMOC emissions in real time.

Somenath Mitra, professor of chemistry, has invented a new technique for on-line monitoring of toxic chemicals, such as solvents and organic vapors, in air emissions at very low levels. The new device is an automated instrument for continuous monitoring of non-methane organic carbon analysis/  The key element in the device a "microtrap" that gathers organics from the air stream in a sorbent. The technique works much faster than any conventional monitoring systems and increases sensitivity by two or three orders of magnitude, allowing analysis of very low concentrations.

Research Interests

  • Sensors and analytical instrumentation; MEMS, lab-on-a-chip, microfluidics; thin-film sensors and devices using conducting and semiconducting polymers; instrumentation/devices based on membrane separation.
  • Nanotechnology, carbon nanotube synthesis and functionalization.
