In HPLC analysis, especially in gradient elution, some unexpected peaks, which are usually called Ghost peaks, may appear in a chromatogram.

Ghost peaks my appear for many reasons, including residual in injection valve, water pollution impurities and unknown components in sample. Generally, they are caused by impurities from mobile phase.

Welch Ghost-Buster Column can solve this problem easily!

Welch Ghost-Buster column can efficiently adsorb and remove the impurities from mobile phase to eliminate their interference to the target peaks. Installed between the gradient mixer and the sampler, Ghost-Buster column can trap most ghost peaks before HPLC analysis.
