(a) Higher potential sensitivity

(b) Low cost

(c) High volume flow rates

(d) Easy cell accessibility

I had been asked this question at a job interview.

I'm obligated to ask this question of Detection System of Liquid Chromatography in division Chromatography of Analytical Instrumentation

Answer 1

Right option is (c) High volume flow rates

For explanation I would say: Refractive index type detectors have low volume flow rates. It is one of the major advantages of the refractive index type of detectors.
