Latest Patents

John L. Middleton holds a patent for a "Dual-column, dual-detector gas detector and analyzer." This sophisticated device utilizes both a photo-ionization detector and a flame-ionization detector to enhance the detection of gases. In survey mode, it samples ambient air and leverages the outputs from both detectors to identify the presence of multiple gases. The analysis mode then processes fixed-volume air samples through two elution columns with distinctive properties. By evaluating the arrival times of gas peaks at each detector, the system generates two candidacy lists for gases, cross-checking them to confirm identifications. The device's portability is notable, achieved by minimizing the need for isothermal ovens and reducing hydrogen quantities. Additionally, it simplifies temperature corrections for the elution columns, demonstrating Middleton's commitment to efficiency and practicality in design.
