| Abstract: | An high resolution ESI QQQ TOFMS coupled with three sect quadrupoles is reported.The home made instrument in the laboratory has a number of features. It can be used as tandem MS (MS/MS) owing to three sect quadrupoles used in the ion modulation part; the TOFMS analyzer adopted positive negative double extrusion pulse and orthogonal injection way; two grade ion reflector with grids designed by computer simulation, and new micro channel plate (MCP) mounting method. This instrument has already been in working condition after preliminary adjustment, and the resolution over 10,000 was achieved. |
