Latest Patents
One of Abdul Tafreshi's latest patents focuses on vapor detection with high-speed gas chromatography. This invention discloses a method and apparatus for the selective detection of vapors of specific compounds, especially nitrogen-containing compounds. The system utilizes a bypass branch and high-speed gas chromatography to enhance selectivity and sensitivity. It features two gas chromatographs (GCs) alternating in series with two pyrolyzers, allowing for two distinct time intervals of detection. The second time interval captures signals that are delayed and further separated from those in the first interval. The bypass branch diverts a portion of the gas sample flow, preventing interferences in the first detection interval from non-GC-retained compounds that may decompose in the second pyrolyzer. Additionally, the invention includes an arrangement for the rapid and precise heating of vapor concentrator tubes, which focuses vapors before they are injected into a GC.
