Ghost-Guard-LC columns are special columns that effectively remove non-polar impurities from the mobile phase and thus solve the problem of unwanted ghost peaks or poor baselines. In our portfolio you will find ghost columns from the manufacturers Analyte (online shop), Shimadzu (on request) and Welch (online shop).
Ghost-Guard-LC columns are usually installed between gradient mixers and autosamplers.
