Welch Ghost-Buster Column II, 4.0 x 30 mm

Effective Elimination of Ghost Peaks in HPLC Analysis

During HPLC separation, especially in gradient elution or when the system has been used for a long period, sporadic and unpredictable peaks (commonly referred to as “ghost peaks”) are likely to appear. The causes of ghost peaks vary, and the primary ones are impurities in the mobile phase and contamination within the instrument system.

At Welch Materials, we've launched the Ghost-Buster column. It effectively absorbs and removes impurities from the system, thereby preventing interference from impurity on the target peaks.

Product Features

Ghost-Buster Columns not only remove impurities from the mobile phase but also effectively capture contaminants within the plumbing and mixer, eliminating interferences from ghost peaks in analyses, enhancing workflow efficiency, and extending the lifespans of columns and instruments to some extent.

Through further upgrades and refinements, Ghost-Buster Columns II not only achieve superior adsorption of mobile-phase impurities to eliminate ghost peaks, but also address the baseline drift caused by an excessively high initial aqueous proportion in gradient runs, yielding a markedly more stable baseline.
