Amanda B. Dlugasch has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11331596
    Abstract: A chromatography system includes a first chromatography column for receiving and separating a flow stream, a plurality of traps configured to trap a plurality of distinct flow segments exiting the first chromatography column during separation of the flow stream, and a second chromatography column operatively associated with the plurality of traps for receiving and separating the distinct flow segments. The system can include at-column dilution at trapping and separating stages thereof. A chromatography method for operating the chromatographic system includes measuring a plurality of time segments corresponding to a plurality of peaks of a fluid sample flowing through the first chromatographic column, and sequentially fluidly coupling the plurality of distinct flow segments with the corresponding plurality of traps during time segments corresponding to the plurality of peaks.

  • Patent number: 10668406
    Abstract: The present disclosure relates to an enhanced multi-dimensional chromatography system and method using selectable At-Column Dilution to improve compatibility of the interface and transfer between the multiple dimensions. The use of At-Column Dilution (“ACD”) with multi-dimensional chromatography can provide greater retention of the diverted components on subsequent stationary phases, and increase the sensitivity and peak shape of the component(s) separated on subsequent dimensions.
