详细技术说明

Stage of Development:The technology is at an early stage of development. Researchers have successfully simulated EiberΓÇÖs work in the laboratory to show marked improvement in the Signal to Noise Ratio (SNR) which establishes greater efficiency of the suggested device. The patent is awaited for the construction of the prototype. Additional research needs to be pursued prior to achieving commercialization of the device.Future Development:Ongoing research is being performed to test other options that can be incorporated into the technology with emphasis on maximizing mass resolution, using alternative approaches to mass-selective scanning and using alternate ion sources. In the near future, highly advanced data analysis tools will be employed to interpret the unique spectra obtained by the device. Also, a detailed database will be constructed which will be used to indicate the probability of match of the sample with the closest related compound.

*Abstract

The subject technology involves a hand-held portable mass spectrometer utilizing the Loeb-Eiber mass filtering device. The device is designed to operate at pressures above 1 millibar (0.75 Torr) to eliminate the usage of a turbo or ion pump and only requires a small roughing pump for operation. It operates on continuous low power consumption of 100 Watts and without high RF amplitudes. The construction is a laptop sized model with a maximum dimension of 1 ft3 and weight of less than 30 lbs. Software manipulation will be used to run the instrument as well as record and interpret the data. The spectrometer is functionally compatible with miniaturization standards and provides superior resolution to portable Ion Mobility Mass Spectrometers. It can detect gas-phase neutrals (having a concentration greater than 1 part per million) and gas-phase ions from the atmosphere using a robust and flexible ion source.
