ABSTRACT:
A system intended for use in time-of-flight mass spectroscopy for detecting at least one ion species in an ion spectra including a signal acquisition circuit for detecting the ions in the spectra and generating output signals indicative thereof, a sequence and storage control circuit for tagging certain ones of the signals to be stored, a memory circuit for storing the output signals tagged by the sequence and storage control circuit, and a digital signal processor circuit receiving the tagged signals from the memory for summing the tagged data and generating an output signal indicative of a value of the ion species detected. A method for collecting the data is also disclosed. Further, the system of the present invention allows for easy storage of signals to be stored in a mass mapped buffer and addressed via a look-up table without requiring additional software to tag the data. Also, the system and method further provide for two banks of gain memory to update the amplifier gain setting without loss or corruption of data collection.
