The response signal output by the gas chromatograph Chromatography vials chromatographic detector is a continuous analog signal that needs to be converted to a discrete digital signal acceptable to the data processor or computer software by an analog/digital conversion device before being processed by a data processor or computer.
Whether it is a data processor or a computer, before obtaining the information such as the position and size of each peak from the discrete spectral sample data of the gas chromatograph, there are four steps: noise filtering, signal peak detection, Baseline correction, overlapping peak cuts.
This is the end of the introduction of Gas Chromatography Chromatography Data Processing Principle. I hope it can help you.
