Latest Patents

Carnahan's latest inventions include:

1. **Inlet Heating Device for Ion Mobility Spectrometer**: This device is designed to heat the sample stream inlet of an ion mobility spectrometry sensor. By increasing the temperature of the inlet surface, it minimizes the time required for adsorption and desorption processes. This enhancement allows the IMS sensor to better track rapid changes in analyte concentration. An alternate embodiment of this invention also features a flow smoothing device, which reduces turbulence in the fluid flow entering the IMS sensor’s carrier stream inlet. This innovation permits an increase in fluid flow rates that maximize measurement sensitivity without mixing sample and carrier fluid flows.

2. **Recirculating Filtration System for Use with a Transportable Ion Mobility Spectrometer**: This system is intended for gas chromatography applications. It incorporates a pump, filters, and flow sensors connected to an ion mobility spectrometry sensor equipped with a gas chromatograph column at its inlet. The filtration system cleans the sensor's outlet flow, recirculating it back into the system. This setup maintains a constant total flow volume during analysis. Additionally, the multicapillary column is sealed to a heated transfer line, ensuring that analyte species do not adsorb on the transfer line walls.
