Sheathless interface for coupling capillary electrophoresis with mass spectrometry |
| 摘要 |
A sheathless interface for coupling capillary electrophoresis (CE) with mass spectrometry is disclosed. The sheathless interface includes a separation capillary for performing CE separation and an emitter capillary for electrospray ionization. A portion of the emitter capillary is porous or, alternatively, is coated to form an electrically conductive surface. A section of the emitter capillary is disposed within the separation capillary, forming a joint. A metal tube, containing a conductive liquid, encloses the joint. |

1. A sheathless interface for coupling capillary electrophoresis (CE) with mass spectrometry comprising:
a. a separation capillary for performing CE separation; b. an emitter capillary for electrospray ionization; wherein a portion of the emitter capillary is porous or is coated to form an electrically conductive surface, and wherein a section of the emitter capillary is disposed within the separation capillary, forming a joint; and c. a metal tube containing a conductive liquid and enclosing the joint, wherein the emitter capillary and the separation capillary have different diameters.
