[1] A tunable diode laser absorption spectrometer (TDLAS) was modified for high-precision and high-time-resolution formaldehyde (CH 2 O) measurements.. This enhanced system was deployed in both the clean and polluted troposphere, as part of aircraft missions (TOPSE 2000, TexAQS 2000, and TRACE-P 2001) and ground-based missions (SOS 1999)..
Tunable diode laser absorption spectroscopy ( TDLAS) is a technique for measuring the concentration of certain species such as methane, water vapor and many more, in a gaseous mixture.. The advantage of TDLAS over other techniques for concentration measurement is its ability to achieve very low detection limits (of the order of ppbv )..

When a gas has an absorption feature at a specific wavelength, the transmitted intensity declines exponentially with: I ( ν ,t) = I 0 (ν) e -S (T) g (ν,ν0) n L.. With n being the number density of the molecular absorbers, I 0 (ν) the initial laser intensity and I (ν,t) the intensity detected after the probe with an absorption length L..

The tunable diode laser absorption spectrometers (TDLAS) operate by measuring the amount of a laser light that is absorbed as it travels through the gas being measured.. Because the sensor does not have contact with the process and there are no moving parts, maintenance is minimized, which decreases downtime and reduces the long-term cost of ownership (LTCO)..
