Latest Patents

One of his latest patents is for a method and device for trace vapor detection. This invention involves sampling air suspected of containing cocaine vapors and passing it through a filtration system that removes particulate matter while binding the vapors for further analysis. A preferred associated compound-vapor is ecgonidine methyl ester (EDME), which serves as a marker for the presence of cocaine. The device is designed with sampling, filtration, and vacuum port components, making it easy to attach to a container and suction source for air sampling.

Another significant patent is a thermally-releasable sample collecting device. This device features a pistol-shaped casing with a blunt-ended probe and an adsorber tube that can slide within a collar. The adsorber tube is designed to draw air through the probe and then allow carrier gas to pass along the tube, entraining thermally released samples for analysis. This innovative design enhances the efficiency of sample collection in various applications.
