Journal of chromatographic science

Kirkland JJ, Yau WW, Stoklosa HJ, Dilks CH.
PMID: 893648
J Chromatogr Sci. 1977 Aug;15(8):303-16. doi: 10.1093/chromsci/15.8.303.

Chromatographic resolution and analysis accuracy can be seriously affected by broadening of very sharp bands associated with both high-performance size-exclusion chromatography and other liquid chromatography methods using less than 5 micron particles. The effect on column plate count by...
