Question

Gas chromatography: which of these effects result from slow injection of a large sample volume?

A) Increased separation efficiency
B) Decreased resolution
C) Shorter retention times
D) Reduced sensitivity

Answer 1

Slow injection of a large sample volume in gas chromatography can result in shorter retention times and reduced sensitivity, but does not affect separation efficiency and resolution.

Step-by-step explanation:

Gas chromatography separates components of a sample by their different affinities to the stationary and mobile phases. When a large sample volume is injected slowly, it can result in shorter retention times and reduced sensitivity, but it does not affect separation efficiency and resolution.
