The Ghost-Buster Column Kit is an HPLC accessory designed to minimize unwanted ghost peaks and baseline fluctuations during chromatographic analysis. Ghost peaks are unexpected signals that may appear in chromatograms, particularly during gradient elution. They can interfere with analyte detection, complicate peak identification, and reduce the reliability of analytical results.
These unwanted signals are frequently associated with contaminants in mobile phases, solvent impurities, and residues accumulated in HPLC system components such as mixers and tubing.
The Ghost-Buster column helps capture and remove certain contaminants before they reach the analytical column, supporting cleaner chromatograms and more consistent HPLC performance.
Key Features and Benefits
- Ghost Peak Reduction: Helps minimize unexpected chromatographic peaks caused by certain system and mobile-phase contaminants.
- Baseline Stability: Supports improved baseline consistency during gradient HPLC analysis.
- Mobile Phase Cleaning: Adsorbs selected impurities from the mobile phase.
- Improved Analytical Reliability: Helps reduce unwanted interference during trace compound analysis.
- Complete Connection Kit: Includes four PEEK fittings and two PEEK tubes.
- High Pressure Resistance: Designed for maximum operating pressure of 40 MPa.

Installation Instructions
For optimal performance, install the Ghost-Buster column between the gradient mixer and the autosampler, positioning it before the autosampler.
- Prepare the HPLC system and check all connections.
- For a new column, flush with 80% methanol in water at 1.0 mL/min for 15 minutes before installation.
- Connect the Ghost-Buster column between the gradient mixer and autosampler.
- Use compatible PEEK tubing and fittings to establish secure connections.
- Check system pressure and chromatographic performance before starting analytical runs.
Important: Avoid installing the Ghost-Buster column after the autosampler, as it may adsorb sample components and interfere with analytical results.
Precautions and Maintenance
- Not all mobile-phase impurities can be adsorbed by the Ghost-Buster column.
- Ion-pairing reagents may be retained by the column and can affect analyte retention times or peak shapes.
- Evaluate chromatographic performance when using ion-pairing mobile phases.
- Monitor adsorption efficiency during use and replace the column when its performance declines.
- The column is not designed for unlimited reuse.
- Ensure that the operating pressure does not exceed 40 MPa.
Frequently Asked Questions
1. What is a Ghost-Buster column used for?
It is used in HPLC systems to capture certain mobile-phase and system contaminants that may cause ghost peaks and baseline fluctuations.
2. Where should the Ghost-Buster column be installed?
It should generally be installed between the gradient mixer and autosampler, before the sample injection point.
3. Can it be used with isocratic HPLC?
Yes. It generally does not need to be removed when switching from gradient to isocratic elution, provided it does not negatively affect the separation.
4. Does the Ghost-Buster column affect gradient separation?
It adds some extra system volume. The approximate packing volume of a 4.6 × 50 mm column is 400 µL. This may have a limited influence on separation, depending on the HPLC configuration and method.
5. Are special connectors required?
No special connection requirements are specified. Common PEEK tubing and compatible HPLC connectors are recommended.
6. When should the Ghost-Buster column be replaced?
Replace it when its adsorption efficiency decreases or when chromatographic performance indicates that it is no longer effectively reducing unwanted signals.
