Which of the following statements regarding size exclusion chromatography is false? During size exclusion chromatography, the largest compounds elute out first. The elution order of fully excluded compounds follows an inverse diagonal relationship with respect to elution volume. During size exclusion chromatography, the smallest compounds elute out at the end. The elution order of partially included compounds follows an inverse diagonal relationship with respect to elution volume.
