Avoiding Ghost Peaks in HPLC Analysis Using a Ghost Hunter Column
contributed by Phenomenex |
In the process of liquid chromatography ghost peaks often interfere with the separation or quantification of drug analysis. These ghost peaks are usually introduced by impurities in the mobile phase, salts from a buffer solution, or acids and bases. Troubleshooting ghost peaks is both time and labor consuming.
Ghost Hunter, a ghost peak trap column, is designed to deal with this challenge by effectively removing ghost peaks. The Ghost Hunter column is stable in most organic solvents and aqueous buffers over a wide pH range. It has a unique adsorption material with a special structure and high surface activity that effectively absorbs a variety of nonpolar and polar organic impurities. Use of Ghost Hunter column helps in reducing the appearance of ghost peaks and extend the column and instrument lifetime.
