I have a method using HPLC (high performance liquid chromatography).
It states that a 4.6 x 150mm,3um column should be used. (stationary phase : octadecylsilyl silica gel).
I have a 4.6 x 100mm,2.7um column, silica-based, bonded-phase (non-polar) column.
Can you advise if these 2 can be considered equivalent?
