noiseHPLCBaseline noise has a significant contribution to the repeatability of chromatographic measurements. In this study, baseline noise is characterized by calculating its power spectrum and wavelet transform using frontal chromatograms. Wavelet analysis is a very powerful means to detect the heteros...
In this case, it appears that TCheng's flowcell is okay, based on favorable intensity plots, so I think the concern is the peaks on the blanks, probably due to dirty water/glassware/etc. It appeared to me that the high frequency baselie noise was also high, although the plot does not...

From the spectral analysis, it was found easily that a system using a small stroke pump and a wall jet type cell with a plastic formed carbon working electrode had a low level of the baseline noise. The optimization of HPLC‐ECD system was performed by evaluation of the detection limit ...
The stochastic properties of baseline noise in HPLC systems with a UV photo-diode array, photo-multiplier and gamma-ray detector were examined by dividing the noise into auto-correlated random process (Markov process) and an independent process (white noise). The present work focused on the ...

Agilent Podcast:Tip #5: Seeing Baseline Noise and Drift, Ghost Peaks or Negative Peaks with HPLCLCGCSpectroscopy
if there is too little light energy you will see noise. However, I have also forwarded your data to other chemists at Waters, but I believe the reference energy will provide a clue. Also just for completeness what is the flow rate. Did you actually run the HPLC separation on the ACQUITY...
