<p>A detection scheme for time-of-flight mass spectrometers is described that extends the dynamic range of spectrometers that use counting techniques while avoiding the problems of crosstalk. It is well known that a multiple anode detector capable of detecting different fractions of the incoming particles (6) may be used to increase the dynamic range of a TOFMS system. However, crosstalk between the anode (47) limits the amount by which the dynamic range may be increased. The present invention overcomes limitations imposed by crosstalk by using either a secondary amplification stage (41) or by using different primary amplification stages.</p> |
