Khaled Khleifat Popular answer

I agree with the answer of Polina D. Blagojevic

Udaya Jayasundara

The library should tell you that. By the way your question is too broad

Polina D. Blagojevic

Retention times depend on type of a column (type of stationary phase, capacity, etc), a mobile phase, a flow...and even in the case those are the same, RT of the same compound analyzed on two different instruments will most probably differ... Thus, I am afraid no one would be able to answer your question.
