^eResults reported in [37] by using 60 cm long column with 5 μm pellicular particles.

^fPeak width is calculated using the average value of 30 selected peaks.

^gPeak width is calculated using the average value of all integrated peaks.

^hPeak width is calculated using the median value of all integrated peaks.

ⁱPeak width is calculated using the narrowest value of all integrated peaks.
