Electrospray ionization interface to high pressure mass spectrometry and related methods
摘要
說明書
A microchip capillary electrophoresis (CE) separation with mini-CIT detection was also performed and the results compared with detection using a commercial instrument (Waters Synapt G2). Comparable separation efficiencies were observed with both mass spectrometers. Comparison of mass spectra in the two systems reveal similar features observed, but with wider peak widths in the mini-CIT (12 m/z shown, but has been improved to <5 m/z) than on the Synapt G2 (0.026 m/z) as expected due to high pressure operation.
The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although a few exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the claims. The invention is defined by the following claims, with equivalents of the claims to be included therein.
