Latest Patents

One of his latest patents is titled "On-column derivatization in capillary electrophoresis." This invention presents an on-column derivatization scheme where a liquid or solid labeling reagent is provided in a capillary to react chemically with a sample. This process simplifies the derivatization, separation, and detection by localizing the labeling to a small area within the capillary, achieving fast kinetics and high reaction yield. Another notable patent is "Method and device employing time-delayed integration for detecting." This invention relates to a detection method and apparatus useful in capillary electrophoresis and capillary chromatography. It employs an array of solid-state detectors, such as a charge-coupled device (CCD), operating in time-delayed integration mode. This method increases the effective sampling volume of the flow cell without introducing band broadening, allowing for improved detection limits for fluorophores.
