Table 5.

Pair-wise comparison of retention time means

H-column H-eluents
x̄ = 18.87		 H-column F-eluents
x̄ = 17.76		 F-column H-eluents
x̄ = 20.34		 F-column F-eluents
x̄ = 17.38
H-column H-eluents
x̄ = 18.87		 =
H-column F-eluents
x̄ = 17.76		 < =
F-column H-eluents
x̄ = 20.34		 > > =
F-column F-eluents
x̄ = 17.38		 < ≈ < =

Comparison is made between an entry in the first column and an entry in the first row; x is in min;

“ >” means larger; “<” means smaller; “=” means equal;

“≈” means no statistically significant difference.
