Abstract
A hardware module which operatively carries out a method of compressing mass spectral data, the method comprising: receiving a first signal output from an ion detector of a mass spectrometer; processing the first signal to a digital signal at an output being data frame types representative of the first signal output; temporarily storing the data frame types in a memory block and reading a data frame from the memory block and determining its data frame type and according to its data frame type compressing the data frame according to one or more compression algorithms to generate a compressed data output stream.

A method of compressing mass spectral data, the method comprising:
- receiving a first signal output from an ion detector of a mass spectrometer;
- processing the first signal to a digital signal at an output being data frame types representative of the first signal output;
- temporarily storing the data frame types in a memory block;
- and
- reading a data frame from the memory block and determining a data frame type of the data frame and according to the data frame type compressing the data frame according to one or more compression algorithms to generate a compressed data output stream.
Hardware module for compressing mass spectral data, the hardware module comprising:
- an input to receive input data being a first signal output from an ion detector, the data being characteristic of ion arrival times or ion intensities;
- an analogue to converter, to receive at the input the first signal and process the first signal to a digital digitised first signal;
- a first processor block, the first processor block having logic gates to receive the digitised first signal and process the first signal to data frame types;
- a second processor block comprising a buffer having an input to receive the data frame types and a memory block to temporarily store the data frame types and an output coupled to a compression control logic block for reading a data frame from the memory block and for determining a data frame type of the data frame and according to the data frame type compressing the data frame according to one or more compression algorithms to generate a compressed data output stream.
