How to do chromatographic peak alignment with a timeshift.

Hello,

I was wondering if you guys might know what the best way is to do peak alignment for chromatography. I was thinking of using the alignsignals function. However, I have more than two spectra so I am not sure if that is the best method.

I'm uncertain of which technique I should use to align my chromatographic peaks since they are not centroided and might have varying peak shapes. My goal is to use the peak aligning step so that I can calculate the peak area based signal to noise ratios .I am planning to do this by Integrating the peaks (and noise) over a fixed time window (same time window for peaks and noise.)

I really appreciate all the help!

Many thanks!
