Abstract
A new tunable diode laser absorption spectrometer has been developed capable of long term operations with reduced daily maintenance, space and power requirements. This compact, self aligning unit can be easily adopted for use in laboratory, industrial, mobile or aircraft environments. Designed with fast response (10 Hz) capability, it could be easily utilized to monitor any species of interest in the 3-5 micron spectral range. When sampling at 10 Hz, the system routinely demonstrates a sensitivity of about 5 ppb for CH4.
