Question 10 4 According to the troubleshooting section for column chromatography in the laboratory textbook, select all that applies to why separation would not occur. Incorrect selections deduct points! The adsorbent surface at the top of the column is not flat and horizontal. Sample may have been overloaded onto a small column.
