How Does Column Uniformity Affect HETP?

Points on how column uniformity affect HETP are:

• Columns with uniform packing or stationary-phase coating exhibit consistent HETP values along their length. 
• This consistency indicates that each theoretical separation stage occupies an equal and repeatable length of the column. 
• Non-uniform columns disrupt this pattern by requiring uneven column lengths to achieve individual separation stages.
