| Abstract | The mass range of a quadrupole mass spectrometer with an electrospray source has been increased from m/z 4000 to m/z 8585 by lowering the radio frequency of the quadrupole power supply from 1.00 MHz to 683 kHz. Unit mass resolution at m/z 5030 can be achieved. The sensitivity below m/z 3000 shows only small changes as expected from phase space arguments. Spectra of poly propylene glycol and soybean agglutinin with peaks in the range m/z 4000-7000 are described. (C) 1997 Elsevier Science B.V. |
