CRANE-84853
While ion mobility spectrometer technology has been used since the 1950s to study gas phase ion mobilities and reaction, technology developed by NSWC Crane greatly expands on earlier capabilities. Specifically, the technology allows for higher efficiencies, reduced maintenance costs, and the ability to conduct field calibration with less training and time.

Naval Surface Warfare Center, Crane Division has developed, and reduced to practice, a suite of patents that increase the accuracy and efficiency of ion mobility spectrometry (IMS). Patent 7,078,680 is a software patent that includes an algorithm that allows an IMS to operate at higher efficiency. Patent 7,361,206 is a process and apparatus that decreases maintenance costs by employing a water permable membrane that continuously removes water vapor and reduces the need for filter changes. Patent 7,751,999 enables field calibration of an IMS unit with less training and time.

Advantages:
- Higher efficiencies
- Reduced maintenance costs
- Able to conduct field calibration with less training and time

Potential Applications:
- First responder
- Government
- Military
- Critical infrastructure sites
- Pharmaceutical industry
- Lung disease detection
- Petroleum industry
