Patent number: 11320409Abstract: There is provided an integrated system for liquid separation, such as LC, CE, affinity chromatography, and ion exchange chromatography, comprising a column and end-fittings embedded in a plastic material, such as a thermoplastic polymer. The system may further comprise an electrospray emitter directly connected with the outlet of the column, wherein a substantial part of the emitter is covered with the polymer material. There is also provided a method by which a separation column along with the accompanying end fittings for connection with adjacent liquid conduits is embedded in a polymer matrix. This configuration e.g. ensures that the factory-made, correct attachment of the fittings to the column is preserved (since the matrix prevents further user intervention, accidental or otherwise). Accordingly, the responsibility for the correct attachment of the fittings is shifted from the end user to the manufacturer.Type: GrantFiled: February 17, 2020Date of Patent: May 3, 2022Assignee: PROXEON BIOSYSTEMS ApSInventors: Ole Vorm, Soren Theodorsen, Peter Aagaard Nielsen

Patent number: 10593532Abstract: The invention relates to a liquid junction apparatus for electrospray ionization in a mass spectrometer comprising an electrospray emitter, a capillary conduit assembly for conducting liquid to be electrosprayed, and a union comprising an electrically conductive material, in which the electrospray emitter and the capillary conduit assembly are accommodated in a bottom-sealing butt joint featuring low dead volume while retaining at least one of them pluggable and withdrawable. The liquid junction apparatus facilitates energizing the transmitted liquid to a predetermined voltage level at the liquid junction upstream of an actual emitter tip where electrospraying occurs, while retaining at least one of an electrospray emitter and a capillary conduit assembly pluggable into and withdrawable from a union that comprises a conductive material.Type: GrantFiled: February 18, 2019Date of Patent: March 17, 2020Inventors: Christoph Gebhardt, Peter Aagaard Nielsen, Ralph Kikillus, Christian Meier-Credo
