  • People also ask Does methanol wear out HPLC system components faster? Ethanol, due to its higher viscosity, gives you much higher system pressure than methanol or acetonitrile, and that can wear out hplc system components quicker. Why is ethanol not preferred as the mobile phase in HPLC?

    ethanol_not_preferred_as_the_mobile_phase_in_HPLCSee all results for this question Is ethanol soluble in ethanol? It is because beta sitosterol is hydrophobic as well as soluble in alcohol. If you use ethanol as mobile phase it will dissolve in it therefore no separation will take place as it will be eluted. 1 Recommendation 5th May, 2015 Why is ethanol not preferred as the mobile phase in HPLC?
