Abstract
The invention relates to a portable multi-spectrometry system for chemical and biological sensing in atmospheric air. A portable, spectrometric system integrates multiple spectroscopy theories, combines their advantageous features, and fills the gaps for their limitations. The combined spectrometry system with operations for PLS, IRAS, MAS, MFS, RSS, and MS, will detect particles and chemicals, directly and sequentially, in the same air-stream.
