HPLC
Model 210D
This pair of chromatograms shows a short-term, one minute UV detector noise run on an isocratic 210D
system. The first chromatogram is the raw data, and the second shows it after smoothing.
Expected Performance
UV Detector Noise
This pair of raw and smoothed chromatograms shows 20 minutes of a UV detector noise run on an isocratic
210D system. In the longer time segment, the signal drift is visible.
UV detector noise
averages
approximately
100µV from peak to
