Direct Formaldehyde Sensing at ppb-level Sensitivity and Absolute Accuracy

Introducing the MIRA Pico Formaldehyde portable analyzer from Aeris Technologies, Inc. The Pico Formaldehyde brings to the market place a completely new paradigm : direct measurement (no chemical conversion), sensitivity and absolute accuracy of one part per billion in continuous, real time, and autonomous operation, extreme linearity over multiple decades of concentration, portable, battery-powered, and at a fraction of the cost of analytical solutions displaying comparable performance (e.g. high performance liquid chromatography).

In addition to sharing all the great features of the MIRA Pico platform, the Pico Formaldehyde analyzer uses a unique and proprietary differential approach allowing to cancel out temperature-induced drifts in the reported concentration. The system uses a dual inlet valve switching continuously back and forth between the unaltered air sample and the formaldehyde-scrubbed sample. The result is an unprecedented analytical tool reporting formaldehyde vapor concentration at ppb-level accuracy in real time (2 measurement cycles per minute).

The Pico Formaldehyde analyzer can be used for a wide variety of monitoring applications including:

  • Wood-based panel production
  • Indoor air quality monitoring
  • Coating and varnishing
  • Engineered wood products
  • Painting and corrosion resistant finishes
  • Carpet manufacture & storage
  • Trailer mobile home inspection
  • Automotive emissions
