Rotary evaporator contamination

    1. The problem statement, all variables and given/known data

    Before, I started to evaporate my solvent (butanol) by using rotary evaporator, I greased the ground glass joint holding my flask and bump trapper. Subsequently, I secured my flask sample and the trapper with Keck clip . Is there any possibility that my sample may have been contaminated by grease?
    2. Relevant equations

    3. The attempt at a solution

    There's always something "following" you around --- you "adapt/learn to live with it."
