Abstract

In summary, this paper shows the design and initial performance characterization of a coded aperture miniature mass spectrometer for environmental sensing (CAMMS-ES). CAMMS-ES incorporates spatial aperture coding to break the throughput vs. resolution tradeoff in mass spectrometer miniaturization, and is designed to detect molecules in the mass range of 12-120 amu. Results indicate that the detection limits for methane and toluene using a membrane inlet sample introduction system are 14 ppm and 80 ppb respectively.
