<strong>Ghost-buster Column</strong><br />
During HPLC analysis, especially gradient elution or after long-term system usage, some unexpected peaks, often called &quot;Ghost Peaks&quot;, may appear in the chromatogram. Welch Ghost-Buster Column can effectively remove impurities with low polarity and thus prevents the interference from all kinds of ghost peaks. lt is installed between gradient mixer and injector, which helps remove not only the impurities in mobile phase, but impurities in mixer and pipelines as well.
