QUESTION 5 In a chromatographic separation using a polar stationary phase and a mobile phase composed of 60% hexane and 40% ethyl acetate, two compounds, benzene (peak A) and toluene (peak B), are eluted. The width of peak A at its base is 1.2 min, the width of peak B at its base is 1.3 min, and the retention time of peak A is 5.2 min and peak B is 3.5 min. What is the resolution (Rs) between these two peaks and is it acceptable? R = 1.36. It is not an acceptable resolution. OR=0.74. It is an acceptable resolution. R=1.36. It is an acceptable resolution. R = 0.74. It is not an acceptable resolution.

Transcribed Image Text:QUESTION 5
In a chromatographic separation using a polar stationary phase and a
mobile phase composed of 60% hexane and 40% ethyl acetate, two
compounds, benzene (peak A) and toluene (peak B), are eluted. The width
of peak A at its base is 1.2 min, the width of peak B at its base is 1.3 min,
and the retention time of peak A is 5.2 min and peak B is 3.5 min.
What is the resolution (Rs) between these two peaks and is it acceptable?
R = 1.36. It is not an acceptable resolution.
R = 0.74. It is an acceptable resolution.
R = 1.36. It is an acceptable resolution.
R = 0.74. It is not an acceptable resolution.
