Abstract
Abstract RESPONDING TO THE ANALOG OUTPUT SIGNALS OF CORRESPONDING ANALYTICAL INSTRUMENTS. A PROGRAM IS STORED IN THE MEMORY OF THE DATA PROCESSOR FOR ANALYZING THE SAMPLE SIGNALS TO DERIVE THE TIME OF OCCURRENCE OF THE PEAKS IN THE ANALOG SIGNALS AS WELL AS THEIR AREAS. AN ANALYTICAL INSTRUMENT SYSTEM INCLUDES A PLURALITY OF GAS CHROMATOGRAPHIC ANALYTICAL INSTRUMENTS THAT PRODUCE ANALOG OUTPUT SIGNALS HAVING VOLTAGE PEAKS THAT EXTEND FROM A BASELINE. A PLURALITY OF VOLTAGE-TO-FREQUENCY CONVERTERS ARE COUPLED TO CORRESPONDING ANALYTICAL INSTRUMENTS TO CONVERT THE VOLTAGE OUTPUT SIGNALS THEREOF TO PULSES HAVING A PULSE REPETITION RATE CORRESPONDING TO THE AMPLITUDES OF THE ANALOG SIGNALS. DEDICATED CIRCUITS INCLUDING A PLURALITY OF COUNTERS ARE COUPLED TO CORRESPONDING ONES OF THE VOLTAGE-TO-FREQUENCY CONVERTERS TO COUNT THE OUTPUT PULSES THEREFROM. A DATA PROCESSOR IS PROVIDED FOR RESPONDING TO THE STORED DATA IN SAID COUNTERS. THE DATA PROCESSOR INCLUDES MEANS FOR SAMPLING THE COUNTERS AT INTERVALS TO GENERATE A SEQUENCE OF SAMPLE SIGNALS COR-
