Latest Patents

Barnett's latest patents include the "Automated Thermal Desorption Unit" and the "Polymer Packed Minitube Vapor Sampling System." The Automated Thermal Desorption Unit features a base plate and a pair of spaced apart plates that hold a magazine of tubes. This innovative unit is designed to selectively extract, handle, heat, and reinsert tubes from the magazine. The heating process drives off the contents of the tubes, which are then flushed to clean their interiors. The Polymer Packed Minitube Vapor Sampling System consists of a magazine with multiple sampling tubes, an inlet, and an outlet at a designated sampling position. A tube advancing mechanism sequentially moves the sampling tubes, while an air pump draws air through the inlet, sampling tube, and outlet, allowing for efficient air sampling.
