Which of the following doesnt NOT affect the efficiency of a

Which of the following doesn\'t NOT affect the efficiency of a column (choose all that apply):

a) Internal diameter of the column

b) The chemistry of the stationary phase

c) The flow rate of the carrier gas

d) Eddy diffusion

e) The injection temperature

Solution

Answer-(e) The injection temperature

Description-All factors affects efficiency of a column except Injection temperature because column temerature affect the efficiency Not Injection temperature.

Column efficiency a function of the column dimensions diameter, length and film thickness, the type of carrier gas and its flow rate or average linear velocity.
