μDirac: an autonomous instrument for halocarbon measurements [PDF]

, 2010
We describe a new instrument (μDirac) capable of measuring halocarbons in the atmosphere. Portability, power efficiency and autonomy were critical design requirements and the resulting instrument can be readily deployed unattended on a range of platforms:
