WebThe determination of aromatic acids by ion exclusion chromatography is challenging due to peak tailing and the long retention time of hydrophobic solutes. This review discusses the retention mechanisms and the factors affecting retention, eluents and detection methods used in ion exclusion chromatography of aromatic acids such as mono-, di-, tri- and tetra … Web4 Mar 2010 · ILs can be used as mobile phase additives in reversed-phase chromatography when mixed with other solvents such as methanol and acetonitrile. The addition of ionic liquids as the mobile phase in HPLC decreases the band tailing, reduces the band broadening, and improves the resolution.

Web14 Mar 2024 · One of the most common peak problems in HPLC is peak splitting or broadening. This can be caused by a variety of factors, including column overload, poor column packing, or improper mobile phase composition. In some cases, peak splitting can also be caused by sample matrix effects or poor sample preparation techniques. WebBy subtracting a blank chromatogram, TIPick eliminates chemical signals of blank injections and reduces false positive results. TIPick detects peaks by calculating the S(CCINI) values of extracted ion chromatograms (EICs) without considering peak shapes, and it is able to detect tailing and fronting peaks.
