Claims

The device contains a conversion mode control unit 1, an analog-to-digital converter 2, a digital printing block, an input signal extreme value determination unit 4, a control unit 5, a conversion range setting unit 6, an input signal threshold setting unit 7 and a counter-decoder 8, recorder 9 mass spectra (mass spectrometer). The device operates as follows. The analog signal of the mass spectrometer is fed to the input of the conversion range unit 6, which controls: switching sensitivity of the analog-digital converter 2. The signal when the threshold value specified by the com 7 is exceeded is fed to the input of the analog-digital converter 2. From the output of block 2, the converted to a discrete type signal goes to block 4 of determining the extreme values of the input signal, where the subsequent code is compared with previous and determination of the maximum value. Thereafter, signals from the output of block 4 are fed into a digital printing unit for printing the amplitude code. The output signal from block 1 is fed to the input of the counter-decoder 8. Thus, the registered peak from ghial is counted and the decoder issues a control signal and block 6 for switching the sensitivity of the analog-to-digital converter 2 scale. BjiOK 1 controls the conversion mode of the block's signal signal, controls 5 rewind reverter to accelerated mode to eliminate loss of time on waiting for the next peak of the recorded spectrum. When novicKe is the maximum signal value on the left upstream branch of the peak according to the signal of block 5, the conversion mode control unit 1 puts the scan into slow mode. When registering the last pic in the spectrum during the forward sweep (from left to right), the signal from the output of the counter-decoder 8 is fed to the input of unit 1, after which the sweep is transferred from the forward run to the reverse. In this case, the device operates in a tax manner, with the exception of too; that the counter-decoder 8 works on reading and switches the sensitivity of the scales in reverse order.
