Patent ID: 11467140

Abstract:
Methods and systems for measuring, in a gas stream, an analyte concentration level from a gas chromatography elution peak outputted by a gas chromatography system are provided. The method includes receiving an analyte signal representative of the gas chromatography elution peak in the time domain, converting the analyte signal from the time-domain to the frequency domain, in the frequency domain, preprocessing the analyte signal to distinguish frequencies of the analyte signal, integrating the analyte signal after preprocessing to obtain a redressed analyte signal in the time domain, the redressed analyte signal having a substantially Gaussian shape, and processing the redressed analyte signal to obtain the analyte concentration level. The system includes a detector operable for generating the analyte signal and one or more processors configured for preprocessing and integrating the analyte signal to obtain the redressed analyte signal and processing the redressed analyte signal to obtain the analyte concentration level.
