A high-resolution high masses detector for time-of-flight mass spectrometer

摘要

the invention relates to devices and methods for high-resolution and highly sensitive detection of ions of large masses in the range of about ten thousand to several hundred thousand atomic units of mass in flugzeitmassenspektrometern.in detail, it concerns the conversion of large masses of ions into smaller particles, including charged particles, with normal ionendetektoren for small and medium mass ions can be detected.$a, the invention consists of a thin vielkanalplatte, of a kind used for the sekundu00e4relektronenvervielfachung is used as konversionseinrichtung to use.this, however, is compared with the operation of the sekundu00e4relektronenvervielfachung in reverse polarity), the impact of major ions to the small ions by the vielkanalplatte through the following ionendetektor to accelerate.this device and method leads to a surprisingly low smeared signals and provides high sensitivity for large ions.
