High-Performance Liquid Chromatography (HPLC) is widely used in research to identify and quantify chemical compounds. Read and assess the following statements about this technique.

I - In a size exclusion chromatography, the size of the peak is related to the size of the molecule.

II - In a reversed-phase HPLC separation, an increase in the amount of organic solvent in the mobile phase will decrease the retention time.

III - If compound A has greater affinity for the column packing than compound B, it will be swept through the column more slowly.

IV - Noise, tailing, and split peaks are examples of parameters that must be given to the hardware before the signal acquisition.
