This Information Applies To: Agilent GC Systems Issue The data rate determines the number of sampling points across the chromatographic peak and the sample background. The data rate is based on the width of the analyte speak (in minutes) and the ratio of the analyte signal to the background noise. Background The data rate unit is hertz (Hz), where 1 Hz is one cycle per second. The data rate determines the number of data points taken across the width of the peak, and in the background...
