Xiaobin Xu

If you are sure that the separation is good enough, you can rely on the chromatogram. If you are only interested in the peaks/compositions eluting within one min, it is better to backflush the compositions that may elute after one min. Otherwise, it is possible that you get peaks from your last sample.
